Consider the reaction: N2 + 3H2 $\to$ 2NH3 carried out at constant temperature and pressure. If $\Delta H$ and $\Delta U$ are the enthalpy and internal energy changes for the reaction, which of the following expressions is true?

Question

Consider the reaction: N₂ + 3H₂ $\to$ 2NH₃ carried out at constant temperature and pressure. If $\Delta H$ and $\Delta U$ are the enthalpy and internal energy changes for the reaction, which of the following expressions is true?

$\Delta H$ > $\Delta U$

$\Delta H$ < $\Delta U$

$\Delta H$ = $\Delta U$

$\Delta H$ = 0
