To determine which reaction has $\Delta H = \Delta U$, we use the equation:

$ \Delta H = \Delta U + \Delta n_g \cdot RT $

Where:

$\Delta H$ is the change in enthalpy.

$\Delta U$ is the change in internal energy.

$\Delta n_g$ is the change in the number of moles of gas.

$R$ is the ideal gas constant.

$T$ is the temper
