During some integral number of complete cycles a reversible heat engine absorbs 2800 kJ from a heat reservoir at 1000 K and performs 800 kJ of mechanical work. The engine exchanges heat with two other heat reservoirs one of which is 5400 K and the other at 600K. Determine the heat exchanged (whether absorbed or rejected) with these two reservoirs, the change in entropy of each of the three reservoirs and the change in the entropy of the universe. Draw a Neat sketch of the system
