The rate constant, the activation energy and the Arrhenius parameters of a chemical reaction at $25^{\circ} \mathrm{C}$ are $2.0 \times 10^{-5}$ $\mathrm{s}^{-1}, 100 \mathrm{~kJ} \mathrm{~mol}^{-1}$ and $6.0 \times 10^{14} \mathrm{~s}^{-1}$, respectively. The value of rate constant at very high temperature approaches
$2.0 \times 10^{-5} \mathrm{~s}^{-1}$
infinity
$6.0 \times 10^{14} \mathrm{~s}^{-1}$
$12 \times 10^{-9} \mathrm{~s}^{-1}$
Solution
We have $k=A \mathrm{e}^{-E_{2} / R T}$. When $T ightarrow \infty, k ightarrow A$
