Which consequence results when attempting to operate a Carnot engine beyond fundamental limits?

💡 Explanation

Carnot engine efficiency depends on operating temperature differences; exceeding them increases irreversibility because of increased entropy generation from non-ideal heat transfer. Therefore, the efficiency decreases, rather than the engine exhibiting reversible or perpetual motion.
