The order of reaction may ......... same as molecularity of the same reaction.

Explanation

### Step-by-Step Solution:

1. **Understanding Molecularity**:
- Molecularity refers to the number of reactant molecules that collide in an elementary reaction to form products. It is defined only for elementary reactions, which are single-step processes.

2. **Defining Order of Reaction**:
- The order of a reaction is determined experimentally and is the sum of the powers of the concentration terms in the rate law expression. It can be a whole number, fraction, or zero.
