Which outcome limits performance of endothermic chemical engines?

💡 Explanation

Endothermic engines are limited by maximum possible efficiency, because the Carnot efficiency dictates the upper limit based on operating temperatures; therefore, the engine undergoes irreversibility at the second law efficiency limits, rather than being dictated exclusively by reaction kinetics or material properties.
