What is the integrated rate law for a zeroth-order reaction?

Question

Quizplus · Accepted Answer

The integrated rate law for a zeroth-order reaction is: 
[A]t = [A]0 - kt
where [A]t is the concentration of the reactant at time t, [A]0 is the initial concentration of the reactant, k is the rate constant, and t is the time. 
Option A is incorrect because it has an arbitrary power of [A], S1U1B1. 
Options B, D, and E are incorrect because they represent other integrated rate laws for different order reactions.
