Which parameter increases when irreversible process occurs in Carnot cycle heat engine operating at fixed temperatures?

💡 Explanation

When irreversibilities are introduced into a Carnot cycle heat engine, thermodynamic irreversibility causes entropy generation during heat transfer because of non-equilibrium conditions. Therefore total entropy of the system increases, rather than efficiency, work, or expansion duration which decrease or stay same, because irreversibilities reduce cycle performance.
