![\log \frac{K_2}{K_1}=\frac{E_a}{2.303R}\times [\frac{T_2-T_1}{T_1T_2}]](/tpl/images/0167/7789/e0c66.png)
= rate of reaction at 
= rate of reaction at 
= activation energy
![\log \frac{2K_1}{K_1}=\frac{249000 kJ/mol}{2.303\times 8.314 J/mol K}\times [\frac{T_2-730.6 K}{730.6 K\times T_2}]](/tpl/images/0167/7789/638fd.png)
