Question

Which one of the following statements about the properties of gases is NOT correct?

a. At high pressures, the attractive forces between molecules cause a real gas to deviate from ideal gas behavior, and the van der Waals a factor adjusts for this.
b. At high pressures, the finite size of the molecules causes a real gas to deviate from ideal gas behavior, and the van der Waals b factor adjusts for this.
c. The ratio PV/RT = 1 for one mole of an ideal gas.
d. The ratio PV/nRT < 1 because of repulsive interactions between the molecules.
e. The ratio PV/nRT > 1 because of the finite size and repulsive force of the molecules.
