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