Which outcome results when exceeding compression limits during adiabatic compression within a Carnot engine?

A)Increased irreversibility and entropy generation
B)Maximum efficiency becomes thermodynamically achievable
C)Isothermal expansion phase spontaneous reversal
D)Constant volume cooling at constant pressure

💡 Explanation

Exceeding compression creates higher temperature gradients; therefore, increased irreversibility and entropy generation occurs because turbulent kinetic energy dissipates as heat, which opposes the ideal quasistatic Carnot assumption, rather than achieving maximum efficiency.
