(d) Calculate the difference between enthalpy and internal energy changes (AH – AU) for the following reaction of perfect gases at 298 K: N₂ (g) + 3H₂ (g) → 2 NH3 (g) [4 marks] (e) Consider 1 mol of a pressurised ideal gas, which expands isothermally at 300 K from 1.00 dm³ to 11.00 dm³. Calculate the work (w) done for the following: (i) The expansion against a constant external pressure of 1.00 atmosphere. [1.00 atm = 101325 Pa]. [2 marks] (ii) A reversible expansion: for this derive mathematically the equation you would use to calculate the reversible work of isothermal expansion of an ideal gas. [5 marks]
