The correct difference between first and second order reactions is that
(1). 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.
(2). a first-order reaction can be catalyzed; a second-order reaction cannot be catalyzed.
(3). 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
.
(4). 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.
