Question

The rate of chemical reaction doubles with every 10 o C rise in temperature. If the reaction is carried out in the vicinity of 22 o C , the activation energy of the reaction is (Given R = 8 . 3 J K - 1 mol - 1 , ln 2 = 0 . 69 and ln 3 = 1 . 1 ), 1 . 69 kJ mol - 1, 0 . 169 kJ mol - 1, 49 . 8 kJ mol - 1, 498 J mol - 1
