| - | Not to be confused with the fugacity coeffient $\phi$, which is a pressure value used to model abbaviations from the ideal gas model pressures. In some contexts this fugacity is called activity. | + | Not to be confused with the fugacity coeffient $\phi$, which is a pressure value used to model abbaviations from the ideal gas model pressures. The unitless normalized fugacity coeffient is called thermodynamic activity $a$, which is closer to $z$. The so called activity $a_B$ on the other hand is the non-ideal analogue of a concentration. |
