Question
The correct difference between first- and second-order reaction is that
Options
A.
the rate of a first-order reaction does not depend on reactant concentration; the rate of a secondorder reaction does depend on reactant concentrations.
B.
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
C.
a first-order reaction can be catalyzed; a second-order reaction cannot be catalyzed.
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
Solution
(t1/2)1st order = Independent of Concentration
