For a reaction X + Y ⟶ Z, rate[X]. What is (i) molecularity and (ii) order of reaction?

A.(i) 2, (ii) 1✓ Correct

B.(i) 2, (ii) 2

C.(i) 1, (ii) 1

D.(i) 1, (ii) 2

Explanation

Question says X + Y both are involved in collision to form product then molecularity as per the question is 2. Since Rate Law is given as 1 R= k X , order is 1.
