A cycling heat engine receives 325 kJ of energy from a reservoir with a temperature of 1000 K and supplies 125 kJ of energy to another reservoir with a temperature of 400 K. Meanwhile, 200 kJ of work is produced in the cycle. Do you think this cycle is reversible, irreversible or impossible? Why is that?
