Which outcome increases within a Carnot heat engine utilizing R-134a when the condenser pressure rises unexpectedly?

💡 Explanation

The Carnot cycle's efficiency depends on temperature difference; increased condenser pressure raises the cold reservoir temperature. Increased temperature reduces ΔT; Cycle efficiency decreases sharply because the Carnot efficiency is (1-Tc/Th), therefore Carnot efficiency is impacted rather than the other properties.
