![\log (\frac{K_2}{K_1})=\frac{Ea}{2.303\times R}[\frac{1}{T_1}-\frac{1}{T_2}]](/tpl/images/0463/0011/6d953.png)
= rate constant at 
= 
= rate constant at 
= 
= activation energy for the reaction = ?
= initial temperature = 
= final temperature = 
![\log (\frac{k}{40k})=\frac{Ea}{2.303\times 8.314 J/mol K}[\frac{1}{298K}-\frac{1}{277 K}]](/tpl/images/0463/0011/8d4b8.png)
