Question

Deviation from the ideal gas behaviour of a gas can be expressed as

• A. $Z = \frac{\rho}{VRT}$
• B. $Z = \frac{pV}{nRT}$
• C. $Z = \frac{nRT}{pV}$
• D. $Z = \frac{V}{RT}$

Hint:

For ideal gas, $Z = 1$.

Answer 1

The Correct Option is B

Step 1: Conceptual Understanding:
Compressibility factor measures deviation from ideal gas behaviour.
Step 2: Explanation in Detail:
$Z = \frac{pV}{nRT}$; for ideal gas, $Z = 1$.
Step 3: Therefore, Stating the Final Answer
$Z = \frac{pV}{nRT}$.
