Chemical Kinetics Numerical Problem Areas for JEE Main 2026

Chemical Kinetics is the study of the speed of chemical reactions and the influence on the reactions. The numerical problems in this section tend to challenge ideas of reaction rates, order and molecularity, calculation of rate constant, and calculating the built-in rate law:

• Calculating Rate Constants: Problems on zero, first, and second-order reactions where students calculate rate constants using concentration vs time data.

• Half-life Calculations: Determining half-life for reactions of various orders; these are common and straightforward numerical problems.

• Determining Reaction Order: Given concentrations and rates, calculate the order of reaction using the rate equation data.

• Integrated Rate Law Problems: Using integrated rate equations to determine concentrations at a given time.

• Arrhenius Equation: Calculating activation energy or frequency factor from rate constants at different temperatures.

• Reaction Mechanism-Based Problems: Simple calculations involving rate-determining steps in multi-step reactions.
