Question

The kinetics of the reaction below were studied and it was determined that the reaction rate did not change when the concentration of B was tripled. The reaction is ________ order in B.

A + B → P
A) zero
B) first
C) second
D) third
E) one half

Answer 1

The reaction is zeroth order in B.

Step-by-step explanation:

The kinetics of the reaction A + B → P were studied, and it was found that the reaction rate did not change when the concentration of B was tripled. This information tells us the order of the reaction with respect to B. Since the reaction rate is unchanged when the concentration of B is tripled, it means that the reaction is zeroth order in B. Therefore, the answer to the question is option A) zero.
