Please, solve this problem in detail:

A refrigeration unit operates between two heat reservoirs with temperatures of 240 nd 320K. The refrigeration unit itself has a temperature of 230K during heat addition from the 240K reservoir and a temperature of 340K during heat rejection to the 320K reservoir. The COP of the actual unit is 2.00 , and the heat-transfer rate from the 240K reservoir is 1000kJ/min. Determine the entropy production rate, in kJ/minK, for a the refrigeration unit itself b. the low-temperature heat-transfer process c. the high-temperature heat-transfer process d. Which process has the largest irreversibility? Now, for the same temperatures and a heat-transfer rate of 1000kJ/min, reduce the actual COP to 1.50. Again, determine the entropy production rate in kJ/minK for e. the refrigeration unit itself f. the low-temperature heat-transfer process g. the high-temperature heat-transfer process h. Which process now has the largest irreversibility
