Question

Which of the following expressions correctly represents the van der Waals equation of state?

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

Answer 1

The correct option is D $(P+\frac{n^{2}a}{V^2})(V-nb)=nRT$

Van der Waal's equation $=$ $(P+\frac{n^{2}a}{V^2})(V-nb)=nRT$

Hence, option D is correct.
