Read the Assertion and Reason below and choose the correct option. — States of Matter and Gaseous State Chemistry Question

💡 Solution & Explanation

Statement I is correct. Intermolecular attractive forces pull molecules inward, reducing the force with which they strike the walls (causing real pressure to be lower than ideal pressure). Statement II is correct and explains Statement I: without the inward backward pull of attractive forces, the molecules strike the walls with greater unattenuated speed and momentum, thereby exerting a higher pressure. Therefore, correct answer is A.
