Which risk increases when a Carnot engine with fixed thermal reservoirs approaches reversible operation?

💡 Explanation

As a Carnot engine approaches reversibility, the isothermal processes performed during its cycles approach infinitesimally slow rates; this causes a practical infeasibility because real-world timescales cannot permit such slow operation; therefore, cycle duration increases rather than decreased power; other parameters are more related to deviation.
