Binary coefficients such as binary diffusion coefficients, Henry coefficients.
More...
Binary coefficients describe the relations of a mixture of two components. Typical binary coefficients are Henry coefficients or binary molecular diffusion coefficients.

Range of validity: T = {278.12 ; 636.46} approximations beyond this range are increasingly incorrect. However, close to the critical the values are more, again.
