Which characteristic increases when a Carnot engine cycle operates irreversibly?

💡 Explanation

Irreversible processes generate entropy because heat transfer happens through non-equilibrium states, involving viscous behaviours; therefore, total entropy continuously accumulates, rather than having constant value like in pure reversible Carnot cycles under similar controlled conditions.
