Which risk increases when the Carnot cycle’s hot reservoir has limited enthalpy?

A)Reduced cycle efficiency and output
B)Increased engine component corrosion rate
C)Higher internal combustion chamber pressures
D)Decreased heat rejection rates downstream

💡 Explanation

Reduced cycle efficiency and output occur because the limited enthalpy restricts the heat input, impairing the Isothermal Expansion mechanism. Therefore, the engine performs poorly, rather than facing component corrosion or combustion issues, which arise under different failure conditions.
