The activation energy for a reaction is 122137.5 J/ mol. If the rate constant at 330K is 0.5 min^-1, then the value of rate constant (in min^-1) at 360K by Arrhenius law is ____(a) 20.42(b) 18.65(c) 30.12(d) 12.32I have been asked this question during an online interview.My question is based upon Kinetics of Homogeneous Reactions topic in chapter Kinetics of Homogeneous Reactions of Chemical Reaction Engineering

Answer»

Correct answer is (a) 20.42

For EXPLANATION I would say: ln(\(\FRAC{k_2}{k_1}) = -\frac{E}{R} (\frac{1}{T_2} – \frac{1}{T_1}) \)

ln(\(\frac{k_2}{0.5}) = -\frac{E}{8.314} (\frac{1}{360}- \frac{1}{330}) \)

K2 = 20.42 min^-1.
