The Van Der Waals Equation of State for a Real

Multiple Choice

The van der Waals equation of state for a real gas is In this equation, the van der Waals constant, a, represents a correction for

A) a positive deviation in the measured value of P from that for an ideal gas due to the finite volume of space occupied by molecules of a real gas.
B) a negative deviation in the measured value of P from that for an ideal gas due to the finite volume of space occupied by molecules of a real gas.
C) a positive deviation in the measured value of P from that for an ideal gas due to the attractive forces between the molecules of a real gas.
D) a negative deviation in the measured value of P from that for an ideal gas due to the attractive forces between the molecules of a real gas.
E) a positive deviation in the measured value of P from that for an ideal gas due to the finite mass of the molecules of a real gas.
