the relation between energf activation and rate constant K1 K2 and temperature T1 T2

Open in App

Solution

Dear student,
The relation between activation energy, rate constant and temperature is given as follows:

$\ln (\frac{K_{2}}{K_{1}}) = \frac{E_{a}}{R} (\frac{1}{T_{1}} - \frac{1}{T_{2}}) w h e r e E_{a} i s t h e a c t i v a t i o n e n e r g y K_{1} a n d K_{2} a r e t h e r a t e c o n s \tan t s T_{1} a n d T_{2} a r e t e m p e r a t u r e s$
