Question
Write the expression showing the relation between enthalpy change and internal energy change for gaseous phase reaction.
✓
Answer
$\Delta H=\Delta U+\Delta n_g R T$
where $\Delta H$ is change in enthalpy,
$\Delta U$ is a change in internal energy,
$\Delta n _{ g }$ is the difference between the number of moles of products and those of reactants.
