Problem
The half-life of the thermal decomposition of compound C was measured at several initial concentrations, as shown.
[C]0 (M) 0.20 0.40 0.80
t1/2 (s) 55 27 14
Based on these data, which of the following plots would be expected to give a straight line, and what is the order of the reaction with respect to C?
(a) ln[C] versus time; first order
(b) [C]1 versus time; second order
(c) [C] versus time; zero order
(d) [C]1 versus time; first order
