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.

Calculate the entropy change (∆S) for the reaction of 2 moles of solid NH4Cl with 1 mole of NaOH in a coffee cup calorimeter at a constant temperature of 25°C. The reaction takes place in 100 mL of water and produces 2 moles of NH3 and 1 mole of NaCl in solution. Assume that the specific heat capacity of water is 4.18 J/g·K and that the final solution temperature after the reaction is complete is 25°C.
