Question Style in MHT CET Chemical Kinetics PYQs

Every question in this PDF is a single-correct MCQ. Most are numerical problems that use a rate law or an integrated rate equation.

Question Style	What it Tests
Rate law and rate of reaction	The rate of a reaction from the rate law when the rate constant and the concentration of NOBr are given, and the way the rate of a reaction is written for 2SO₂ + O₂ → 2SO₃
Order of reaction	The order of reaction from a rate law, and the order with respect to each reactant and the overall order for a rate law that contains NO and H₂
First order reactions	The rate constant from the slope of a graph for a first order reaction, the half life at 300 K when the half life at 400 K is 900 minutes, and the time taken for a given consumption of reactant
Arrhenius equation	Which form of the Arrhenius equation, written with log A and Ea / 2.303R, is correct
Role of a catalyst and theory	The role of a catalyst in a reaction, and the reaction that is first order in one reactant and zeroth order in another

How to Use the Chemical Kinetics PYQ PDF for MHT CET

Start with the 2025 and 2026 papers first, because they hold 98 of the 252 questions.
Write the integrated rate equations for zero order and first order reactions once and note the unit of k for each order.
For the Arrhenius equation, remember the form log(k₂/k₁) = (Ea / 2.303R) × (1/T₁ − 1/T₂).
Solve year-wise PYQs by timing yourself, as time management is crucial.
Re-attempt only the questions you got wrong, and note which formula or step you missed.
