A researcher follows the progress of a reaction using spectroscopic methods. The half-life, ( $t_{1 / 2}$ ), is found to depend on the initial concentration of the reactant. This evidence suggests that the reaction is following first order kinetics.

Question

Quizplus · Accepted Answer

The statement is contradictory. If the half-life of a reaction depends on the initial concentration of the reactant, it implies that the reaction is not following first order kinetics. First order reactions have a constant half-life, independent of the initial concentration of the reactant. Therefore, the given evidence suggests that the reaction is not following first order kinetics.
