Question

The rate of a reaction quadruples when the temperature changes from 300 to 310 K . The activation energy of this reaction is: (Assume Activation energy and pre-exponential factor are independent of temperature; ln ( 2 ) = 0 . 693 ; R = 8 . 314 J - mol - 1 K - 1 ), 53 . 6 kJ mol - 1, 214 . 4 kJ mol - 1, 107 . 2 kJ mol - 1, 53 . 6 kJ mol - 1
