Which outcome occurs when a heat engine operates irreversibly during isothermal expansion?

💡 Explanation

When heat engine operation is irreversible, entropy increase happens because friction and thermal gradients dissipate energy, reducing useful work output according to the Second Law. Therefore less work output results, rather than increased efficiency/reduced temperatures that ideal Carnot engine scenarios would allow.
