Vedclass · Answer

(C) For an ideal gas,the heat of reaction at constant pressure $(q_{p})$ and constant volume $(q_{v})$ are related by the enthalpy change equation.Since $\Delta H = \Delta E + \Delta n RT$ and $\Delta H = q_{p}$ (at constant pressure) and $\Delta E = q_{v}$ (at constant volume),Therefore,$q_{p} = q_{v} + \Delta n RT$.

For an ideal gas,the heat of reaction at constant pressure and constant volume are related as:
