The rate constant, the activation energy and the Arrhenius parameter of a chemical reaction at 25°C are 3.0 × 1 0 - 4 s - , 104.4 kJ m o l - 1 and 6 × 1 0 14 s - 1 respectively. The value of the rate constant as T → ∞ is

k = A e - E a / R T (Arrhenius equation) when T → ∞ k = A e 0 , or k = A Thus k = 6 × 1 0 14 s - 1

The rate constant, the activation energy and the Arrhenius parameter of a chemical reaction at $25°C$ are $3.0 \times 1 0^{- 4} s^{-}$ , $104.4 kJ m o l^{- 1}$ and $6 \times 1 0^{14} s^{- 1}$ respectively. The value of the rate constant as $T \to \infty$ is

Options:

Answer:

Solution:

$k = A e^{- E a / R T}$ (Arrhenius equation)
when $T \to \infty$
$k = A e^{0}$ , or $k = A$
Thus $k = 6 \times 1 0^{14} s^{- 1}$
