Two moles of an ideal gas are compressed isothermally (100°C) and reversibly from a pressure of 10 atm to 25 atm, then the free energy change is :

(a) +15.482 kJ

(b) +10.462 kJ

(d) +3.364 kJ

Explanation:

For isothermal reversible process,

W_ev = -2.303 nRT log P₁/P₂

= -2.303 × 2 × 8.314 × 373 log 10/25

= + 5684.1 J = 5.684 kJ
