Which outcome occurs when using a real-world heat engine to emulate Carnot cycle at increasing frequency?

A)Reduced efficiency due to friction losses
B)Increased power output from faster cycles
C)Improved efficiency from shorter cycles
D)Decreased entropy generation during transformations

💡 Explanation

When cycle frequency increases, irreversible processes like friction dominate because the system spends less time near equilibrium, increasing dissipation and consequently reducing the actual efficiency compared to the ideal Carnot efficiency. Therefore reduced efficiency results, rather than increased power, improved efficiency, or decreased entropy, as these are offset by real-world losses.
