A reversible engine supplies heat from two constant temperature sources at 800 K and 400 K and rejects heat to a constant temperature sink at 200 K. If it develops 100 kW and rejects 3500 kJ of heat per minute, then QA and QB are
= 4500 kJ/min,
= 4000 kJ/min
= 3000 kJ/min,
= 4000 kJ/min
= 5000 kJ/min,
= 4500 kJ/min
= 5000 kJ/min,
= 5000 kJ/min
