B) A power cycle operating between two reservoirs receives energy QH by heat transfer from a hot reservoir at TH = 2000 K and rejects energy Qc by heat transfer to a cold reservoir at Tc = 400 K. For each of the following cases determine whether the cycle operates reversibly, irreversibly, or is impossible: (a) QH = 1200 KJ, Wcycle = 1020 KJ. (b) QH = 1200 KJ, Qc = 240 KJ. (c) Wcycle = : 1400 KJ, Qc = 600 KJ (d) n= 40%
