The volume correction term in the van der Waals equation is present because:
A)barometers are inaccurate
B)molecules are diatomic
C)molecules attract each other
D)molecules occupy volume
E)molecules repel each other

Question

Quizplus · Accepted Answer

The van der Waals equation incorporates a correction term for the volume occupied by the molecules themselves, which is not accounted for in the ideal gas law. This term is represented by "nb" in the equation, where "n" is the number of moles of gas and "b" is a constant related to the molecular volume. Therefore, the correct choice is (D) molecules occupy volume.
