D) ln[A]
E) -k

Question

Quizplus · Accepted Answer

For a zeroth-order reaction, the rate of reaction is independent of the concentration of the reactants. The rate equation is given by rate = k, where k is the rate constant. When plotting the concentration of reactant A ([A]) versus time for a zeroth-order reaction, the slope of the line is equal to -k, indicating a linear decrease in concentration over time.
