Question

The term that accounts for intermolecular force in vander Waals' equation for non ideal gas is:

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

Answer 1

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

The correct answer should be - $(p+\frac{a}{V^2})$.

The van der Waals’ equation of state for 1 mole of the non-ideal gas.is denoted by the equation

$=p+\frac{a}{V^2}(V-b)=RT$.

The factor $(p+\frac{a}{V^2})$ is accountable for the inter-molecular force,

whereas the term ($V-b$) is accountable to the molecular volume.
