Estimate the value of the acentric factor, w, for nitrogen, using tabular vapor pressure andcritical data. The vapor pressures of nitrogen at 85 and 90 K,respectively, are 2.291 and 3.608 bars.(Note: Do not linearly interpolate thevapor-pressure data, but assume that the vapor pressurePvis related to the absolutetemperature by the relation, ln Pv= A/T + B.)
