What is the over all order of reaction which has the following rate expression? Rate = $k[A]^{1/2} [B]^{3/2}$
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → Two
The overall order of the reaction is two.
The overall order of a reaction is obtained by adding the powers of the concentration terms in the rate law.
Given rate expression: Rate = k[A]¹⁄² [B]³⁄²
Order with respect to A = 1/2
Order with respect to B = 3/2
Overall order = 1/2 + 3/2 = 2
Therefore, the reaction is a second-order reaction.
