Problem : The rate constant, the activation energy and the Arrhenius parameter of a chemical reaction at 25°C are 3.0 × 10–4 s–1 , 104.4 kJ mol–1 and 6.0 × 1014 s–1 respectively the value of the rate constant as T →∞ is

(A) 2.0 × 1018 s–1

(B) 6.0 × 1014 s–1

(C) ∞

(D) 3.6 × 1030 s–1

Solution: $\large K = A e^{E_a/RT}$

When T → ∞

K → A

A = 6 × 1014 s–1
