Value of compression factor z for critical constants?

Approved Tutor Answer12 Years agoThe extent of deviation of a real gas from ideal behaviour is studied using the term compressibility factor (Z).
Negative deviation - Z<1 (i.e . attraction dominates)
Positive deviation - Z>1 (i.e. replusion dominates)
The closer the gas is to its critical point or its boiling point, the more 
deviates from the ideal case.
