Which outcome occurs when a heat engine operates irreversibly?

💡 Explanation

Reduced efficiency occurs because irreversibility causes entropy generation due to microscopic friction and thermal gradients using the Second Law. Therefore, less work exits the engine output rather than operating reversibly and maximizing conversion.
