A heat pump (HP) and a heat engine (HE) operate between a high temperature reservoir at TH= 600 K and low temperature reservoir at TL= 300 K as shown in

the figure. (a)&(b) For the heat pump (HP) with the conditions in the table below, determine if the heat pump is irreversible, reversible or impossible for steady state operation. Justify your answers based upon both the first and second laws of thermodynamics. (c)&(d) For the heat engine (HE) with the conditions in the table below, determine if the heat engine is irreversible, reversible or impossible for steady state operation. Justify your answers based upon both the first and second laws of thermodynamics.
