Question

A mixture of 2 moles of carbon monoxide and one mole of oxygen in a closed vessel is ignited to convert carbon monoxide to carbon dioxide. If $\Delta H$ is the enthalpy change and $\Delta E$ is the change in internal energy, then

Professor PC Thomas Classes · Answer

Reaction: $2	ext{CO} + 	ext{O}_2 	o 2	ext{CO}_2$, $\Delta n_g = -1$. $\Delta H = \Delta E + \Delta n_g RT \Rightarrow \Delta H = \Delta E - RT \Rightarrow \Delta H < \Delta E$.
