Question

The reaction 2 A + B 2 → 2 AB is an elementary reaction. For a certain quantity of reactants, if the volume of the reaction vessel is reduced by a factor of 3 , the rate of the reaction increases by a factor of _____ . (Round off to the Nearest Integer).

Reaction : 2 A + B 2 ⟶ 2 AB As the reaction is elementary, the rate of reaction is r = K . [ A ] 2 B 2 on reducing the volume by a factor of 3 , the concentrations of A and B 2 will become 3 times and hence, the rate becomes 3 2 × 3 = 27 times of initial rate.
