Use the van der Waals equation of state to calculate the pressure of 3.20 mol of CH4 at 479 K in a 5.60 L vessel. Van der Waals constants can be found in the van der Waals constants table. 𝑃= atm Use the ideal gas equation to calculate the pressure under the same conditions. 𝑃= atm Under these conditions, would you expect CH4 or CCl4 to deviate more from ideal behavior? Why? CH4 because it occupies a smaller volume and it has greater dispersion forces between molecules. CH4 because it occupies a larger volume and it has smaller dispersion forces between molecules. CCl4 because it occupies a larger volume and it has greater dispersion forces between molecules. CCl4 because it occupies a smaller volume and it has greater dispersion forces between molecules. CH4 because it occupies a smaller volume and it has smaller dispersion forces between molecules. CCl because it occupies a larger volume and it has smaller dispersion forces between molecules.
