Which irreversible outcome primarily reduces carnot engine efficiency?

💡 Explanation

Imperfect thermal contact initiates thermal resistance, thus the temperature gradient across contacts reduces energy available for work during heat transfer via the mechanism of heat leakage. Therefore, efficiency plummets rather than optimizing toward reversibility.
