Abstract

Abstract:

A differential equation for the fugacity coefficient of the single-component non-ideal gas is derived. As for the multi-component non-ideal gas, differential forms for each component are also derived. A total fugacity coefficient is defined for this mixed non-ideal gas and its relationship with the fugacity coefficient of each component is obtained. In the similar way, the activity coefficients of each component of the non-ideal solution are derived, a total activity coefficient of the non-ideal solution is defined and its relationship with the activity coefficient of each component is also obtained. Comparisons between the expressions of the fugacity coefficient and activity coefficient are made finally and discussed in details.

Key words: Non-ideal gas, Non-ideal solution, Fugacity, Fugacity coefficient, Activity, Activity coefficient
