A piston-cylinder assembly contains 0.5 kmoles of CO2 gas (CO2, M= 44). The CO2, initially at P1 = 2.5 MPa and T1 = 750 K, undergoes a process until it is at P2 = 0.03 MPa and T2 = 420 K. Assume that carbon dioxide is an ideal gas and its specific heats are not constant. Changes inpotential and kinetic energies are negligible. Given that the change in entropy of the system is 4.9562 kJ/K, and W = +6370 kJ from state 1 to state 2. i) Calculate deltaQ ii) Calculate the entropy generated for this process at an average T of 720 K
