Question

The activation energy, rate-constant and Arrhenius parameters of a chemical reaction at 25^oC are 104.4 KJ mol^-1, 3.0 x 10^-4s^-1, 6.0 x 10¹⁴s^-1respectively. The value of rate-constant in $s^{- 1}$ at $T \to \infty$ is (write your answer by dividing by 10¹⁴)

Answer:

6.00

Solution:

$k = A \cdot e^{- Ea / RT}$ (Arrhenius equation)

As $T \to \infty$

k → A

i.e., $k = A = 6 \times 1 0^{14} {sec}^{-1}$

TestHub · Accepted Answer

k = A · e - Ea / RT (Arrhenius equation) As T → ∞ k → A i.e., k = A = 6 × 1 0 1 4 sec -1
