The compressibility factor for a real gas is
1
\(\frac{{PV}}{{RT}}\) and should never be equal to unity.
2
\(\frac{{PR}}{{VT}}\) and should always be unity only
3
\(\frac{{PV}}{{RT}}\) and should always be more than unity
4
\(\frac{{PT}}{{VR}}\) and should always be more than unity
5
\(\frac{{PT}}{{RV}}\) and should always be unity only
