Question

Which of the following statements about the arrhenius equation are NOT correct ?

(A) The pre exponential factor become equal to the rate constant of the reaction at temperature T → ∞

(B) When the activation energy of the reaction → zero, the rate becomes independent of temperature.

(C) The terme–Ea/RT represents the fractions of the molecules having energy is excess of the threshold value.

(D) On raising temperature , rate constant of the reaction of greater activation energy increases less rapidly than that of the reaction of smaller activation energy.

Answer 1

Correct Answer is: (D) On raising temperature , rate constant of the reaction of greater activation energy increases less rapidly than that of the reaction of smaller activation energy.

K = Ae-Ea /RT A = K T → ∞

Ea = 0
