K=Ae- Ea / RT as T arrow ∞ ;K arrow A

$2 \times 1 0^{18} se c^{- 1}$

$16 \times 1 0^{14} se c^{- 1}$

Infinity

$4 \times 1 0^{- 4} se c^{- 1}$

$K = A e^{- E a / RT}$
as $T \to \infty; K \to A$

Q. The rate constant, Arrhenius constant (pre-exponential factor) of the chemical reaction and the activation energy of a chemical reaction at 25∘C are 4×10−4sec−1 16×1014sec−1 and 200kJ/mol respectively. The value of rate constant at T→∞ is.

2×1018sec−1

16×1014sec−1

Infinity

4×10−4sec−1

K=Ae−Ea/RT as T→∞;K→A

$2 \times 1 0^{18} se c^{- 1}$

$16 \times 1 0^{14} se c^{- 1}$

$4 \times 1 0^{- 4} se c^{- 1}$

$K = A e^{- E a / RT}$
as $T \to \infty; K \to A$
