First Order Kinetics Means

Question

First order kinetics means:
A) The rate of a reaction is independent of the amount of reactant measured.
B) The rate of the reaction varies directly with the amount of reactant measured.
C) The rate of the reaction varies with the square of the amount of the reactant measured.
D) More information is needed to answer this question.
E) None of these is correct.

Accepted Answer

First order kinetics implies that the rate of the reaction is directly proportional to the concentration of one reactant. This means as the concentration of the reactant increases, the rate of reaction increases linearly, which is described in option B.
