STANDARD Chemistry Molecularity and Order MCQ Question
For a reaction, X + Y → Z, rate ∝ [X]. What are the molecularity and order of reaction?
2 and 1
2 and 2
1 and 1
1 and 2
Correct Answer
Detailed Explanation
The molecularity of a reaction is the number of molecules that come together to react in an elementary step. Since the rate is proportional to [X], the order with respect to X is 1, and the overall order is 1. The molecularity is 2 because two reactants are involved.
