Tardigrade Admin · Accepted Answer

K = Ae e - Ea / RT =(6.5 × 1012 s -1) e -26000 K / T ( Ea /8.314)=26000 Ea =216.164 kJ / mol .

Q. The equation
$k = (6.5 \times 1 0^{12} s^{- 1}) e^{- 26000 K / T}$
is followed for the decomposition of compound $A$ . The activation energy for the reaction is ___ $k J m o l^{- 1}$ . [nearest integer]
(Given: $R = 8.314 J K^{- 1} m o l^{- 1}$ )

$K = A e e^{- E a / RT} = (6.5 \times 1 0^{12} s^{- 1}) e^{- 26000 K / T}$
$\frac{E a}{8.314} = 26000$
$E a = 216.164 k J / m o l .$

Q. The equation k=(6.5×1012s−1)e−26000K/T is followed for the decomposition of compound A. The activation energy for the reaction is ___kJmol−1. [nearest integer] (Given: R=8.314JK−1mol−1 )

K=Aee−Ea/RT=(6.5×1012s−1)e−26000K/T 8.314Ea​=26000 Ea=216.164kJ/mol.
