k = A ⋅ e - Ea / RT (Arrhenius equation) As T arrow ∞ k arrow A i.e., k = A =6 × 1014 sec -1

Q. 30. The activation energy, rate-constant and Arrhenius parameters of a chemical reaction at 25∘C are 104.4KJmol−1,3.0×10−4s−1,6.0× 1014s−1 respectively. The value of rate-constant in s−1 at T→∞ is (write your answer by dividing by 1014 )

k=A⋅e−Ea/RT (Arrhenius equation) As T→∞ k→A i.e., k=A=6×1014sec−1

$k = A \cdot e^{- E a / RT}$ (Arrhenius equation)
As $T \to \infty$
$k \to A$
i.e., $k = A = 6 \times 1 0^{14} se c^{- 1}$
