A power cycle operates between three thermal reservoirs at T1=800 KT_1 = 800 \text{ K}, T2=500 KT_2 = 500 \text{ K}, and T3=300 KT_3 = 300 \text{ K}. In one complete cycle, the working fluid absorbs 1000 J1000 \text{ J} from reservoir 1, rejects 300 J300 \text{ J} to reservoir 2, and rejects 600 J600 \text{ J} to reservoir 3. The entropy change of the working fluid over the complete cycle is zero. What can be concluded about this cycle?
