Question

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 HINT: Check Van der Waals equation.

Answer 1

E

Step-by-step explanation:

The vander waals equation

`(P+n^2a/V^2)(V-nb)`=nRT

The factor n^2a/V^2 accounts for the attractive forces between the gases molecules whereas nb accounts for the decrease in volume occupied by the gas. Therefore, correct option would be E. None of the above have BOTH of the two factors accurately stated
