NCERT Grade 12 Chemistry Chapter 4, Chemical Kinetics deals with average and instantaneous rate of reaction and the factors affecting these. Some elementary ideas about the collision theory of reaction rates are also given in this chapter. After studying this chapter, students will be able to define the average and instantaneous rate of a reaction; express the rate of a reaction in terms of change in concentration of either of the reactants or products with time; distinguish between elementary and complex reactions; differentiate between the molecularity and order of a reaction; define rate constant; discuss the dependence of rate of reactions on concentration, temperature and catalyst; derive integrated rate equations for the zero and first order reactions; determine the rate constants for zeroth and first order reactions; describe collision theory.
Rate of a Chemical Reaction, Factors Influencing Rate of a Reaction, Dependence of Rate on Concentration, Rate Expression and Rate Constant, Order of a Reaction, Molecularity of a Reaction, Integrated Rate Equations, Zero Order Reactions, First Order Reactions, Half-Life of a Reaction, Pseudo First Order Reaction, Temperature Dependence of the Rate of a Reaction and Effect of Catalyst and Collision Theory of Chemical Reactions are the topics discussed in this chapter. NCERT Grade 12 Chapter 4, Chemical Kinetics holds a total weightage of 5 marks in the final examination.
