Strategy and Tips for Preparation of Physical Chemistry for IIT-JEE

Physical chemistry plays a very vital role in the preparation of chemistry for IIT-JEE and other chemistry competitions. Being mathematical in nature, it appears to be somewhat tough to the students. However, it becomes relatively easier, if you use the RRP (Reading, Revision, and Practice) strategy for the preparation of Physical Chemistry.

The analysis of papers of previous years reveals that the following are the hot spots of Physical chemistry for the preparation of IIT-JEE-       

Chemical  Equilibrium

  • Criteria of Equilibrium state
  • Relation between Kc and Kp and its applications
  • Derivation of expression for equilibrium constant (Kc and Kp) for different reactions
  • Concentration quotient (Qc) and its relation with Kc.
  • Numerical based on equilibrium constant (Kc and Kp)

Ionic  Equilibrium

  • pH and numerical based on pH
  • Relation between degree of dissociation and ionization constant 
  • Salt hydrolysis
  • Solubility product (Ksp) and derivation of  Ksp for different electrolytes
  • Theory of precipitation
  • Common ion effect with examples
  • Buffer solutions and their types with examples
  • Buffer capacity


  • Open, Closed and Isolated systems with examples
  • Different types of processes with mathematical criteria
  • Extensive and Intensive properties with examples
  • The first law of thermodynamics and numerical based on it
  • State and Path functions with examples
  • Relation between ΔH and ΔE and its applications
  • Entropy (S) and numerical based on entropy
  • Free energy (G) and numerical based on Free energy 
  • Spontaneity and its criteria
  • Hess’s law and numerical based on Hess’s law  

Redox Reactions

  • Balancing of redox reactions
  • Calculation of oxidation number
  • Electrode potential and Cell potential
  • Electrochemical cell
  • Electrochemical Series
  • Nernst equation and numerical based on Nernst equation


  • Calculation of  the number of atoms per unit cell in different types of unit cells
  • Packing efficiency and numerical based on packing efficiency
  • Crystal density and numerical based on crystal density
  • Imperfections in solids especially Schottky and Frenkel defects
  • F- centers
  • Magnetic properties of solids
  • Electrical properties of solids
  • Piezoelectric effect


  • Modes of expressing the concentration of solutions especially molarity, molality and mole fraction, and numerical
  • Raoult’s law and numerical based on Raoult law
  • Ideal and nonideal solutions
  • Positive and negative deviation from Raoult’s law
  • Colligative properties
  • Relative lowering in vapor pressure
  • Elevation in boiling point
  • Depression in freezing point
  • Osmotic pressure
  • Numericals based on colligative properties
  • The equation for ideal solution/ vant Hoff equation
  • Exo and endo osmosis and reasoning questions
  • Vant Hoff factor
  • Relation between vant Hoff factor (i) and degree of dissociation (α)

Chemical Kinetics

  • Expression of the rate of the reactions
  • Difference between molecularity and order of the reactions
  • Pseudo order reactions with examples
  • The equation for zero/first-order reactions and numerical based on these reactions
  • Activation energy
  • Role of catalyst
  • Arrhenius equation and numerical based on Arrhenius equation 
  • Collision theory

Electro Chemistry

  • Conductivity, molar conductivity, and Numericals
  • Effect of dilution on conductivity and molar conductivity
  • Cell constant and its experimental determination
  • Kohlrausch law and numericals
  • Nernst equation and numerical based on Nernst equation
  • Lead storage cells especially reactions involved in charging and discharging
  • Fuel cells

Surface Chemistry

  • Difference between physical and chemical adsorption
  • Difference between lyophilic and lyophobic colloids
  • Bredig’s arc method
  • Peptization
  • Dialysis and Electrodialysis
  • Tyndall effect
  • Electrophoresis
  • Hardy- Schultze rule
  • Protection of colloids
  • Emulsion and its types
  • The Cleansing action of soap

In fact, the final selection in IIT-JEE stands on the following four pillars-  

(1) Teacher selection

It is the first and the most important criteria to crack IIT-JEE. A teacher of academic or below standard can never let you prepare well for IIT-JEE. So, you should select the best mentor that can prepare you well for IIT-JEE.

(2) Matter selection

For competitive preparation what is not to study is more important than what to study. You should emphasize more on important and relevant topics (hot spots) and practice more on quality study materials rather than being trapped in rubbish materials floating in the market.

Always remember, if your mentor selection is well then he would provide you the best and relevant study materials and therefore, material selection would become automatically well.

In my opinion, you should concentrate on NCERT books that are Encyclopedia of IIT-JEE and you should improve your application part by revision and solving practice papers and previous year’s papers within the prescribed time frame again and again.

(3)Time for starting preparation

When to start preparing for IIT-JEE? It is one of the most frequently asked questions by the IIT-JEE aspirants. In my opinion, you should start your preparation from class 11 and should maintain your tempo till the examinations. If you start too early then it would not be easy for you to maintain your pace for a longer time period and it would develop a frustration in you that is very dangerous for you and your preparation.

(4) Hard work

It is the fourth important pillar of your preparation to crack IIT-JEE in the First Attempt. You have selected the best mentors who are providing you the best study materials but you are not serious in your preparation but just wasting your time, then not even God can make you selected in IIT-JEE. In fact, there is no shortcut to success, except hard work. So, you should maintain consistency in your preparation. The regular study, regular revision, and solving practice problems and previous year’s papers in a specified time frame are the keys to your selection.

Important Tips for Preparation of IIT-JEE

(1) Select a good mentor of Chemistry. Several educational channels and the best mentors of Chemistry are available on YouTube for free. You may follow one of them rather than wandering here and there.

(2) Centralize your study to the NCERT books and one or two reference books of organic Chemistry. Don’t follow too many books otherwise, you would not be able to complete your syllabus. Always remember, different books differ being only nineteen or twenty in text quality, but never differ of being nineteen and twenty-five. 

(3) Follow quality notes of a good mentor. Don’t run behind the brand, but run behind the concise and effective notes of your mentor.

(4) Prepare your own capsule notes for revision.

(5) Maintain consistency and regularity in your preparation.

(6) Revise the prepared topics regularly. Always remember, revision is not a waste of time but it makes you perfect. Always keep in mind that, “Revision is division” i.e. Revision improves your marks and ultimately your rank in the final selection.

(7) Solve practice problems and previous year’s papers in the specified time frame. It would help you to finish your paper timely in the final examination.

(8) Always be confident in your preparation, but never be overconfident. Always read the question carefully and then answer. You usually make mistakes in overconfidence and it has to be reduced.
