Rate Constants of Reactions

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 20 kJ mol^–1. If k₁ and k₂ are the rate constants of first and second reaction respectively at 300 K, then In $\frac{{{k_2}}}{{{k_1}}}$ will be ……... (nearest integer) [R=8.3 J K^–1 mol^–1]
