Because (OH/OP)T=CPHJ-T, the change in enthalpy of a gas expanded at constant temperature can be calculated. To do so, the functional dependence of μJ-T on P must be known. Part A Treating Ar as a van der Waals gas, calculate AH when 1 mole of Ar is expanded from 324 bar to 1.69 bar at 375 K. Assume that μJ-T is independent of pressure and is given by J-T= [(2a/RT) - b]/CP,m, and Cp,m = 5R/2 for Ar. Express your answer with the appropriate units. AHm = Submit Part B O μÅ Value Request Answer Units ? What value would AH have if the gas exhibited ideal gas behavior?
