Dear Sohan ,

 

Arrhenius equation - 

Ea = -RTln(k/A)

where A is the frequency factor for the reaction, R is the universal gas constant, T is the temperature (in kelvins), and k is the reaction rate coefficient, Ea is activation energy.

Given K2=3k1 at T2 = T1 + 10 + 273

Use the above formula..
