What is the correction term in the pressure for real gas in comparison to the ideal gas?


A) $\frac{n^{2}}{V^{2}}$

B) $\frac{aV^{2}}{n^{2}}$

C) $\frac{an^{2}}{V^{2}}$

D) $\frac{an^{2}}{V^{}}-nb$

Answer:

Option C

Explanation:

 According to van der Waal's correction for pressure for real -gases , the pressure correction is given by  

 $p+ \frac{an^{2}}{V^{2}}$.

 $\therefore$  Correction  term for pressure of a real gas =$\frac{an^{2}}{V^{2}}$

 and option (c) is the correct answer
