Consider an ideal gas contained in a vessel. If the intermolecular interactions suddenly begin to ac — States of Matter and Gaseous State Chemistry Question

💡 Solution & Explanation

Intermolecular attractive forces exert an inward pull on the gas molecules approaching the container walls. This backward pull reduces the net momentum with which they strike the wall, causing the macroscopic pressure of the gas to decrease relative to an ideal gas. Therefore, correct answer is A.
