Q1: Which of the following terms of Vander Walls equation of state for a non-ideal gas accounts for intermolecular forces ?

ANS:A - RT

In the Van der Waals equation of state for a non-ideal gas, the term (𝑉−𝑏)(V−b) accounts for the volume occupied by the gas molecules themselves, and 𝑅𝑇RT represents the ideal gas pressure. The term that accounts for intermolecular forces is 𝑎/𝑉2a/V2, where 𝑎a is the Van der Waals constant related to the strength of the intermolecular forces. Therefore, none of the provided options directly represent the term that accounts for intermolecular forces in the Van der Waals equation of state.
