Question

The rate of reaction becomes four times when the temperature changes from 293 K to 313 K. Calculate the energy of activation (Ea) of the reaction assuming that it does not change with temperature. (R = 8·314 J K -1 mol-1)

Answer 1

log k2/k1 =    Ea/ 2.303 * 8.314 (1 / 293 - 1/ 313)

on calculation

         Ea = 1057266.674/20 = 52863.33 J mol^-1
