A nonideal gas obeys the equation of state PVm=RT+(alpha x P) where alpha is a function of T only. An investigator obtains pressure as well as volume data for this gas at a fixed temperature. Not knowing the actual equation of state she fits her data to a virial equation of state. In terms of the quantities appearing in the actual equation of state, explain what will she obtain for the second virial coefficient?
