The van der Waals equation for real gases recognizes that

Question

(A) the molecular atrractions between paritcles of a gas decreases the pressure exerted by the gas
(B) the non-zero volumes of gas particles effectively decrease the amount of "empty space" between them
(C) gas particles have non-zero volumes and interact with one another
(D) molar volumes of gases of different types are different
(E) All of the above statements are correct

would the correct answer be (E)?

Answer 1

(C) says it best; the others are vague or do not tell the whole story.

(D) is not necessarily true, and whatever differences there between are between gases are very small

Answer 2

E is the answer, you are correct
