  • Correct answer
    C
    2
  • D
    3

Solution

For an elementary reaction, the molecularity is defined as the total number of reactant molecules participating in the reaction.

Given the elementary reaction: $\text{A} + \text{B} \rightarrow \text{products}$

The number of reactant molecules is $1$ (for $\text{A}$) $+ 1$ (for $\text{B}$) $= 2$.

Therefore, the molecularity of the reaction is $2$.

Answer: 2

Hence, the correct answer is option: 'C'.
