The term that corrects for the attractive forces present in a real gas in the van der Waals’ equatio — States of Matter and Gaseous State Chemistry Question

💡 Solution & Explanation

The Vander Waal’s equation can be written as- 2 2 ( / )( ) P n a V V nb nRT The constant ‘a’ gives the measure of intermolecular forces of attraction. Hence, the pressure correction term which account for attractive forces in real gas is 2 2 n a V . The constant b gives the measure of molecular size.
