In the nitrogen liquefaction process, nitrogen gas is pre-cooled from 365 K and 50 bar to 80 K and 2 bar. This pre-cooled nitrogen is then liquefied (we are not currently modeling the liquefaction step). On this assignment, we are assuming ideal gas behavior. Required:a. Devise two distinct reversible non-flow processes (any number of steps) for accomplishing this change of state. b. Calculate ΔU each process on the basis of 1 mol of N2 gas. c. Calculate ΔH for each process on the basis of 1 mol of N2 gas. d. On a scale of 0 (not confident) to 3 (entirely confident), how confident are you that the assumption of ideal gas behavior is valid? Justify your answer.
