1. For a reversible carnot cycle starting with an isothermal expansion with 2.50 mol of an ideal gas with a Cv = 5/2R as a working substance. The baths are at 298K and 825K, and Va = 2.25L Vb = 10.5L Vc = 134L Vd = 28.7L. a) What is the change in U, H, S, G, A for the whole cycle. b) What is the total work? Wt = Wab + Wbc + Wcd + Wda = Wab = Wbc = Wcd = Wda = c) What is the total heat? Wt = -qt= d) What is the efficiency? e = 1 - Tc/Th =
