Calculate the change in chemical potential for a mole of carbon dioxide gas expanded from 1 atm to 0.1 atm at 298 K. At this temperature CO2 obeys the virial
equation of state with B' = -0.010 atm-1. Vlll. ( 16 points) 0.1 mole of an ideal gas (CD = 28.2 J/K/mole) is taken from 298 K and 1 atm pressure
to 398 K and 2 atm pressure. Find q, w, AU and AH for this process, being careful to specify the path followed by
the process in your calculation ...
