The data listed below are claimed for a power cycle operating between hot and cold reservoirs at 1500 K and 450 K, respectively. For each case, determine whether the cycle operates reversibly, operates irreversibly, or is impossible. (a) QH = 600 kJ, Wcycle = 300 kJ, QC = 300 kJ (b) QH = 400 kJ, Wcycle = 280 kJ, QC = 120 kJ (c) QH = 700 kJ, Wcycle = 300 kJ, QC = 500 kJ (d) QH = 800 kJ, Wcycle = 600 kJ, QC = 200 kJ

The data listed below are claimed for a power cycle operating between hot and cold reservoirs at 1500 K and 450 K, respectively. For each case, determine whether the cycle operates reversibly, operates irreversibly, or is impossible.

(a) QH = 600 kJ, Wcycle = 300 kJ, QC = 300 kJ

(b) QH = 400 kJ, Wcycle = 280 kJ, QC = 120 kJ

(c) QH = 700 kJ, Wcycle = 300 kJ, QC = 500 kJ

(d) QH = 800 kJ, Wcycle = 600 kJ, QC = 200 kJ
