Which outcome occurs when a reversible heat engine operates isothermally?

💡 Explanation

Entropy change approaches zero for a fully reversible process because changes happening isothermally means heat transfer balances perfectly. Therefore, the net entropy change vanishes, rather than work reaching some maxima or exergy decaying under these conditions.
