The rate constant of the reaction at temperature 200 K is 10 times les – InterviewSolution

1.	The rate constant of the reaction at temperature 200 K is 10 times less than the rate constant at 400 K.What is the activation energy of the reaction ?
Answer» `1842.4" R"` `921.2" R"` `460.6" R"` `230.3" R"` SOLUTION :At `T_1=200 K,` if `k_1=k,` then at `T_2 = 400 K, k_2=20 k ` `log""(10k)/k=E_a/(2303R)(400-200)/(400xx200)" or "E_a=9212R`.
