What is the half-life for a zeroth-order reaction?

Question

Quizplus · Accepted Answer

The half-life of a zeroth-order reaction is given by t1/2 = [A]0/2k, where [A]0 is the initial concentration of the reactant and k is the rate constant. This equation is equivalent to option D, t1/2 = [A]/2k, since [A]/[A]0 = 1. Option A is incorrect because it is not a valid expression for half-life. Option B is incorrect because it is the expression for the time required for a first-order reaction to reach a certain fraction of its initial concentration, not the half-life. Option C is incorrect because it is the expression for the half-life of a first-order reaction. Option E is incorrect because it is the expression for half-life of a second-order reaction.
