Question

The correct difference between first- and second-order reactions is that

• A. the rate of a first-order reaction does not depend on reactant concentrations; the rate of a second-order reaction does depend on reactant concentrations
• B. a first-order reaction can be catalyzed; a second-order reaction cannot be catalyzed
• C. the half-life of a first-order reaction does not depend on [A]0 ; the half-life of a second-order reaction does depend on [A]0
• D. the rate of a first-order reaction does depend on reactant concentrations; the rate of a second-order reaction does not depend on reactant concentrations

Answer 1

Answer: (C)

the half-life of a first-order reaction does not depend on [A]0 ; the half-life of a second-order reaction does depend on [A]0

Answer 2

The correct option is (C) :the half-life of a first-order reaction does not depend on [A]0 ; the half-life of a second-order reaction does depend on [A]0.
