Chemistry 2710 Spring 2000 Quiz 10

Name:

The following second-order rate constants were obtained for the reaction between 2-tolyl isocyanate and 1-butanol:

T ( $^\circ\mathrm{C}$)	0.0	7.0	15.0	25.0
k ( $\mathrm{L\,mol^{-1}s^{-1}}$)	$4.04\times 10^{-5}$	$7.72\times 10^{-5}$	$1.29\times 10^{-4}$	$2.50\times 10^{-4}$

Calculate the activation energy and preexponential factor for this reaction.

Notes: $R = 8.3145\,\mathrm{J\,K^{-1}mol^{-1}}$. To convert degrees Celsius to Kelvin, add 273.15. Drawing a graph is optional.
