Calculate the pressure exerted by Ar for a molar volume of 1.31 L mol 1 at 426
Question:
Calculate the pressure exerted by Ar for a molar volume of 1.31 L mol–1 at 426 K using the van der Waals equation of state. The van der Waals parameters a and b for Ar are 1.355 bar dm6 mol–2 and 0.0320 dm3 mol–1, respectively. Is the attractive or repulsive portion of the potential dominant under these conditions?
