(c) A theoretical engine that operates on the Carnot cycle receives heat from a reservoir at 900 K at a rate of 10 kJ/s and rejects the waste heat to the ambient air at 300 K. The entire work output of the heat engine is used to drive a refrigerator that removes heat from the refrigerated space at 268 K and transfers it to the same ambient air at 300 K. Determine: (i) The maximum rate of heat removal from the refrigerated space and; (ii) The total rate of heat rejection to the ambient air.
