Question

According to Arrhenius equation, rate constant(k) is proportional to ___________

(a) Activation Energy (E)

(b) e^E

(c) e^1/E

(d) e^-E

This question was addressed to me in exam.

My doubt stems from Effect of Temperature on reaction rate in division Reaction Dynamics of Engineering Chemistry I

Answer 1

Correct option is (d) e^-E

Easiest explanation: According to Arrhenius equation, k = Ae^-Ea/RT. So, rate constant(k) is proportional to e^-E.
