This is a noncubic EOS consisting of a Carnahan–Starling repulsion and a Redlich–Kwong attraction term. It usually performs better than the original Redlich–Kwong EOS.

The critical compression factor of this EOS is fixed. It is not possible for this EOS to match all 3 critical conditions.

adjustable parameters: 2
