which can be rearranged in the volume-explicit form: RT

The truncated virial eqn [28] is only applicable to gases at densities that are less than about half the critical density. One of the advantages of the virial equation, however, is that virial coefficients can be calculated from intermolecular potential functions. Also, statistical mechanics provides rigorous expressions for the composition dependence of the virial coefficients. Thus, the mixture second virial coefficient is given by:

The calculation of K values is therefore reduced to the calculation of fugacity coefficients in the equation of state approach and, at moderate pressures, to the calculation of activity coefficients in the activity coefficient approach.

Global warming is a huge problem which will significantly affect every country in the world. Many people all over the world are trying to do whatever they can to help combat the effects of global warming. One of the ways that people can fight global warming is to reduce their dependence on non-renewable energy sources like oil and petroleum based products.
