In a decompostion reaction, the reaction decays 21.2 times more rapidly at 22°C then at 4 °C. What is the overall activation energy (kJ/mol) of the process ?
Answers: 3
= (4 + 273) K = 277 K
= (22 + 273) K = 295 K
= 21.2![ln \frac{k_{2}}{k_{1}} = \frac{E_{a}}{R} [\frac{1}{T_{1}} - \frac{1}{T_{2}}]](/tpl/images/0507/8404/2d1b4.png)
![ln (21.2) = \frac{E_{a}}{8.314 J/mol K} [\frac{1}{277} - \frac{1}{295}]](/tpl/images/0507/8404/6ffc3.png)
= 115116.914 J/mol
