The van der Waals equation is a modification of the ideal gas equation. What two factors does this equation account for
A) (1) Real gas molecules exert forces on each other. (2) Gas molecules have energy.
B) (1) Real gas molecules exert ionic forces on each other. (2) Gas molecules have energy
C) (1) Real gas molecules exert forces on each other. (2) Gas molecules have volume.
D) (1) Real gas molecules exert ionic forces on each other. (2) Gas molecules have volume.
E) None of the above have BOTH of the two factors accurately stated

Question

Quizplus · Accepted Answer

The van der Waals equation considers two factors: (1) the fact that real gas molecules exert forces on each other and (2) the fact that gas molecules have volume. These factors are not ionic in nature, but rather are due to non-ideal behavior of gas molecules. Therefore, the correct answer is C.
