Chemical Kinetics Part 2

Pre-exponential factors of two different reactions of same order are identical. Let activation energy of first reaction exceeds the activation energy of second reaction by 20kJmol−1. If k1 and k2 are the rate constants of first and second reaction respectively at 300 K , then ln‌
