The decomposition of hydrocarbon follows the equation k = (4.5 × 1011s–1) e-28000K/T

Calculate Ea. For the reaction R

The given equation is k = (4.5 ×1011s-1)e-28000K/T(i)
Arrhenius equation is given by,
k=Ae-Ea/RT(ii)
From equations (i) and (ii), we obtain
EaRT=28000KT
Ea=R×28000K
=8.314JK-1mol-1×28000K
=232792Jmol-1
=232.792Kjmol-1
