Chlorine atoms react with methane, forming HCl and CH3. The rate constant for the reaction was determined to be 3.600×107 at 278 K and 3.050×108 at 317 K. Calculate the activation energy for the reaction. (in kJ mol^-1)

The activation energy for the reaction is 40.143 kJ/mol

Explanation:

To calculate activation energy of the reaction, we use Arrhenius equation for two different temperatures, which is:

where,

= equilibrium constant at 317 K =

= equilibrium constant at 278 K =

= Activation energy = ?

R = Gas constant = 8.314 J/mol K

= initial temperature = 278 K

= final temperature = 317 K

Putting values in above equation, we get:

Hence, the activation energy for the reaction is 40.143 kJ/mol
