Identify the wrong relation for real gases :
- A \(Z=\frac{V_{\text {ideal }}}{V_{\text {real }}}\)
- B \(p_{\text {ideal }}=p_{\text {real }}+\frac{a n^2}{V^2}\)
- C \(V_{\text {real }}=V_{\text {ideal }}-n b\)
- D \(\left(p+\frac{a}{V^2}\right)(V-b)=R T\)
Answer & Solution
Correct Answer
(A) \(Z=\frac{V_{\text {ideal }}}{V_{\text {real }}}\)
Step-by-step Solution
Detailed explanation
Wrong relation about real gases is given in option a. Its correct form is
\(Z=\frac{V_{\text {real }}}{V_{\text {idea }}}\)
(\(Z=\) Compressibility factor)
\(Z=\frac{V_{\text {real }}}{V_{\text {idea }}}\)
(\(Z=\) Compressibility factor)
