A container contains a mixture of nitrogen and hydrogen gas. The volume of the container is 25 liters and the mole fraction of hydrogen is 0.8. The pressure of the gas mixture is 1 bar and the temperature is 25 C. Both gases can be treated as ideal. Part a) Determine the entropy of the gas mixture. Part b) What would be the entropy of each gas if they are kept in separate containers at 1 bar and 25 -C? Part c) The gas mixture from part a) is isothermally compressed until its volume has decreased to 10 liters. Calculate the entropy of the gas mixture after this process is completed. Part d) The gas mixture from part c) is now expanded in an isobaric process until the initial volume of 25 liters has been restored. Calculate the entropy of the gas mixture after this process is completed
