A nonreversible heat engine operates between a high-temperature reservoir at T h

Question

A nonreversible heat engine operates between a high-temperature reservoir atTh= 810 K and a low-temperature reservoir atTc=295K. During each cycle the engine absorbs550J of heat from the high-temperature reservoir and performs224J of work. (a) Calculate the total entropy change?Stotfor one cycle.
J/K
(b) How much work would a reversible heat engine perform in one cycle if it operated between the same two temperatures and absorbed the same amount of heat?
J
(c) Show that the difference in work between the non-reversible engine and the reversible engine is equal toTc?Stot, by calculating both of these quantities.
