Q87 · CSIR NET Chemistry, December 2014
Paper: CSIR NET December 2014 · Subject: Physical Chemistry · Chapter: Chemical Kinetics · Topic: Arrhenius Activation · Marks: 2 · Difficulty: Hard
A reaction A + B + C D follows the mechanism
$\mathrm{A + B \rightleftharpoons AB}$; $\mathrm{AB + C \rightarrow D}$
in which first step remains essentially in equilibrium. If $\Delta H$ is the enthalpy change for the first reaction and $E_0$ is the activation energy for the second reaction, the activation energy of the overall reaction will be given by(a)$E_0$
(b)$E_0 - \Delta H$
(c)$E_0 + \Delta H$
(d)$E_0 + 2\Delta H$
