A plot of this process in temperature-entropy phas
A plot of this process in temperature-entropy phase space forms a perfect rectangle. Fuel cells canviolate one theorem named for this process, and a quantity important in describing it is equal to W over Qsub H and is symbolized eta. Comparing it to other processes proves the equivalence of the Clausius andKelvin statements of the second law of thermodynamics. One implementation of it uses a gas in contactwith hot and cold reservoirs. Its efficiency is one minus the ratio of the cold temperature to the hottemperature. This reversible process has four steps, including both isothermal and adiabatic compressions.For 10 points, name this maximally efficient theoretical engine, named after the French scientist who firstdescribed it
