Homework Statement
Why is it that when considering the compressibility factor of a gas Z we see the value decrease at first and increase as value for Pr increases for an isotherm Tr=1?
Homework Equations
z=1+(Pb/RT)-(a/VRT)
The Attempt at a Solution
It is my understanding that as Pr is low that inter-molecular forces dominate thus making z<1 but as Pr increases the Z factor increases.
I am seeking for clarity
Best Regards,
