The pure component fugacity of a substance can be computed from In (A-S;p dP where z is the compressibility factor (PVIRT), P is the pressure, R is the gas constant, T is the absolute temperature, and V is the specific volume. Using the data in the table, compute the pure component fugac- ity of nitrogen at 0C, 25C, and 50C. Since the data are not equally spaced, use of the trapezoidal rule is suggested to perform the numeri- cal integration
