A power cycle operating at steady state receives energy by heat transfer at a rate QH at TH = 1800 K and rejects energy by heat transfer to a cold reservoir at a rate QC at TC = 600 K. For each of the following cases, determine whether the cycle operates reversibly, operates irreversibly, or is impossible.

(A) QH =500kW, QC =100kW
(B) QH = 500 kW, Wcycle = 250 kW, QC = 200 kW
(C) Hot reservoir at Q = 1000°R
(D) Wcycle =350kW, QC =150kW
