The ratio of the actual molar volume of a gas to the ideal molar volume is _____ of the gas.
- co-volume
- van der Waals factor 'a'
- critical volume
- molar gas constant
- compressibility factor
The Correct Option is
Solution and Explanation
The compressibility factor, denoted as \( Z \), is defined as the ratio of the actual molar volume of a gas to the ideal molar volume.
Mathematically,
\( Z = \frac{V_{\text{m, actual}}}{V_{\text{m, ideal}}} \)
If the gas behaves ideally, \( Z = 1 \). For real gases, \( Z \) deviates from 1.
Correct Answer:
Compressibility factor
