For the elementary reaction , what is the molecularity of the reaction? — Reaction Mechanism Chemistry Question

💡 Solution & Explanation

Molecularity is the number of reacting particles taking part in an elementary step. For $A + 2B \rightarrow 3C$, $1$ molecule of A reacts with $2$ molecules of B. Therefore, the molecularity is $1 + 2 = 3$.
