Question

When the rate of reaction is equal to the rate constant then the order of the reaction is:

A. Zero order
B. First order
C. Second order
D. Third order

Answer 1

The order of the reaction is first order.

Step-by-step explanation:

The order of a reaction refers to the power to which the concentration of a reactant is raised in the rate equation. When the rate of reaction is equal to the rate constant, the order of the reaction is: B. First order. In a zeroth-order reaction, the rate is independent of the concentration of the reactants. In a first-order reaction, the rate is directly proportional to the concentration of one reactant.
