Problem

For the reaction H+ I2 → 2HI calculate the molecularity of the reaction.

A. 0

B. 1

C. 2

D. 3

E. none of these


Solution

We are asked to identify the molecularity of the reaction: H+ I2 → 2HI

The molecularity of elementary reactions is equal to the sum of the number of molecules of reactants involved in the balanced reaction.

The molecularity types based on the number of reactants are:
