Consider the following general reaction: IA+IB → products. Rate of this reaction is expressed as: Rate = K[A]1[B]1 The correct order of reaction and molecularity is:
Correct answer: A. 2:2
- A. 2:2
- B. 2:3
- C. 3:2
- D. 3:3
Explanation
The order of the reaction is second. The molecularity of an elementary reaction is defined as the minimum number of molecules, atoms or ions of the reactants required for the reaction to occur and is equal to the sum of the stoichiometric coefficients of the reactants in the chemical equation of the reaction.

About Chemical Equilibrium
Reversible reactions reach dynamic equilibrium when forward and reverse rates become equal, and Le Chatelier's principle predicts the effect of changing concentration, pressure or temperature. The chapter also covers solubility product, the common ion effect, buffer action and the conditions used in Haber's process, with equilibrium shifts distinguished from changes in the equilibrium constant.
