Calculate the standard enthalpy change (∆H°) for the formation of ammonia (NH3) at 298 K using the following data: N2(g) + 3H2(g) → 2NH3(g) ∆H° = −92.4 kJ/mol Hint: Standard enthalpy change (∆H°) for a reaction is calculated by taking the sum of the standard enthalpies of the products minus the sum of the standard enthalpies of the reactants.
