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
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
a first-order reaction can be catalysed; a
second-order reaction cannot be catalysed
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
