Heat liberated by a given amount of an ideal gas undergoing a reversible isothermal process is 600 cal at 300 K. What is the Gibbs free energy change of the gas in this process?
Options:
Answer:
D
Solution:
Isothermal ideal gas: ΔH = 0 and ΔS = qrev/T = −600/300 = −2 cal/K. ΔG = ΔH − TΔS = 0 − 300 × (−2) = +600 cal. Matches (d).
