Which consequence results when a Carnot engine operates far from equilibrium?

A)Reduced thermal efficiency occurs
B)Increased mechanical work output
C)Isothermal expansion becomes adiabatic
D)Refrigeration cycle becomes spontaneous

💡 Explanation

Reduced thermal efficiency occurs because irreversible processes generate entropy during the cycle; that deviation from equilibrium conditions diminishes available work rather than maintaining ideal Carnot efficiency limited by the temperatures.
