← ScienceWhich risk increases significantly when exceeding an engine's maximum Carnot efficiency?
A)Excessive irreversible entropy generation✓
B)Reduced exergy destruction
C)Lower adiabatic process completion
D)Increased isothermal heat exchange
💡 Explanation
Exceeding Carnot is impossible because it represents the theoretical maximum; any real engine is less efficient; thus, it creates the maximum amount of possible entropy. Therefore, efficiency limitations always result in an increase of irreversible entropy generation, rather than the ideal limits of reversible processes.
