What relationship exists, if any, between vapor pressure and intermolecular forces?

A. an inverse relationship
B. no relationship
C. as intermolecular forces increase, so does vapor pressure
D. a direct relationship



Answer :

Final answer:

Intermolecular forces and vapor pressure have an inverse relationship due to stronger forces holding molecules closer together, making it harder for them to escape.


Explanation:

The relationship between intermolecular forces and vapor pressure is an inverse relationship. As intermolecular forces increase, vapor pressure decreases, and vice versa.

This relationship is due to the fact that stronger intermolecular forces hold the molecules closer together, making it harder for them to escape into the gas phase, resulting in lower vapor pressure.

For example, in a substance with weak intermolecular forces like acetone, the vapor pressure is higher compared to a substance with strong intermolecular forces like water.
