Negative deviation: $Z  1$

Vedclass · Answer

(A) The compressibility factor is defined as $Z = \frac{pV}{nRT}$.For an ideal gas,$Z = 1$,and the plot of $pV$ vs $p$ is a horizontal line.Negative deviation occurs when the curve lies below the ideal gas line,indicating $Z Positive deviation occurs when the curve lies above the ideal gas line,indicating $Z > 1$,which is primarily due to the volume occupied by gas molecules becoming significant at high pressures.

For a real gas,what do negative and positive deviations in the $pV$ vs $p$ plot at constant temperature signify?
