Question

The correct expression for the Van der Waals equation is :

• A. $(p+\frac{a}{n^2{V}^2})(V-nb)=nRT$
• B. $(p+\frac{a^2{n}^2}{V^2})(V-nb)=nRT$
• C. $(p+\frac{a{n}^2}{V^2})(V-b)=nRT$
• D. $(p+\frac{a{n}^2}{V^2})(V-nb)=nRT$

Answer 1

Answer: (D)

$(p+\frac{a{n}^2}{V^2})(V-nb)=nRT$

The correct expression for the Vander Waals equation is $(p+\frac{a{n}^2}{V^2})(V-nb)=nRT$.
Here, the term $\frac{a{n}^2}{V^2}$ represents the pressure correction and the term $nb$ represents the volume correction.
