For a reaction `A + B to` Products, the rate law is ................ Rate `=k [A] [B]^(3//2)` can the reaction be an elementary reaction :

A

Yes

B

No

C

Cannot be determined

D

Data Inadequate

Text Solution

Verified by Experts

The correct Answer is:
B
Hint : During an elementary reaction, the number of atoms or ions colliding to react is referred to as molecularity. Had this been an elementary reaction the order of reaction with respect to B would have been I, but in the given rate law it is 3/2. This indicates that the reaction is not an elementary reaction.
