5. The gas-phase decomposition of ethyl iodide to give ethylene and hydrogen iodide is a first-order reaction. C2H5I ļ C2H4 + HI At 600 K, the value of k is 1.60 Ć 10ā 5 sā 1. When the temperature is raised to 700 K, the value of k increases to 6.36 Ć 10ā 3 sā 1. What is the activation energy for this reaction?

![\log (\frac{K_2}{K_1})=\frac{E_a}{2.303\times R}[\frac{1}{T_1}-\frac{1}{T_2}]](/tpl/images/0519/6420/1504e.png)
= rate constant at 
= 
= rate constant at 
= 
= activation energy for the reaction = ?
= initial temperature = 
= final temperature = ![\log (\frac{6.36\times 10^{-3}s^{-1}}{1.60\times 10^{-5}s^{-1}})=\frac{E_a}{2.303\times 8.314J/mole.K}[\frac{1}{600K}-\frac{1}{700K}]](/tpl/images/0519/6420/54c04.png)
![2.60=\frac{E_a}{2.303\times 8.314J/mole.K}[\frac{1}{600K}-\frac{1}{700K}]](/tpl/images/0519/6420/52269.png)
