15(a) One mole of an ideal gas initially at 300 K and at a pressure of 10 atm undergoes adiabatic expansion. (i) Reversibly and (ii) Irreversibly against a constant external pressure of 2 atm until the final pressure becomes equal to the external pressure. Calculate $\Delta \mathrm{S}_{\text {system }}$ for (i) and (ii). For (ii), express the final answer in terms of R. Given: Molar heat capacity at constant volume $\mathrm{C}_{\mathrm{v}, \mathrm{m}}=3 \mathrm{R} / 2$.
