Question

Consider the following statements related to temperature dependence of rate constants. Identify the correct statements. A. The Arrhenius equation holds true only for an elementary homogenous reaction. B. The unit of A is same as that of k in Arrhenius equation. C. At a given temperature, a Low activation energy means a fast reaction. D. A and Ea as used in Arrhenius equation depend on temperature. E. When Ea >> RT. A and Ea become interdependent. Choose the correct answer from the options given below:

(A) B and C Only
(B) A. C and D Only
(C) A and B Only
(D) B, D and E Only

Prashant Kotian · Accepted Answer

Correct answer: A. Arrhenius equation RT E – a Ae k  So unit of A & K is same. At given temperature. Low activation energy means a fast reaction.
