Question

In van der waals equation, for state of a non-ideal gas, the term that accounts for intermolecular forces is:

• A. $V-b$
• B. $RT$
• C. $(P+\frac{a}{V^2})$
• D. $(RT{)}^{-1}$

Answer 1

The correct option is C $(P+\frac{a}{V^2})$

According to Van der waals equation,
$(P+\frac{a}{V^2})(V-b)=RT$
For one mole of real gas.
In this equation, $(P+\frac{a}{V^2})$, accounts for intermolecular forces.
