Solution
The correct option is D Free space available for the molecules to move about in real gas is smaller than that in ideal gas In a real gas the molecules going to strike the walls of the container are attracted towards interior owing to the intermolecular forces. As a result the moleucules strike the walls with lesser momentum and exert lesser pressure than ideal gas.
Molecules in a real gas have finite size and occupy some volume. Thus the vacant (free) space available for the molecules to move about is somewhat decreased in comparision to ideal gas.
