For an ideal gas, the heat of reaction at constant pressure and heat of reaction at constant volume are related by equation
  1. $\dot{H}+U=P V$
  2. $\mathrm{U}=\mathrm{H}+\mathrm{P} \Delta \mathrm{V}$
  3. $\Delta \mathrm{U}=\Delta \mathrm{H}+\frac{\Delta \mathrm{n}}{\mathrm{RT}}$
  4. $\Delta \mathrm{H}=\Delta \mathrm{U}+\Delta \mathrm{nRT}$

Solution

$\begin{aligned} & q_p=\Delta H \\ & q_v=\Delta U \\ \therefore \quad & \Delta H=\Delta U+\Delta n_g R T\end{aligned}$
