isoequilibrium relationship

https://doi.org/10.1351/goldbook.I03280
A relationship analogous to the @[email protected] but applied to equilibrium data. The equation defining the isoequilibrium temperature \(\beta \) is: \[\Delta _{\text{r}}H - \beta\ \Delta _{\text{r}}S = \text{constant}\] where \(\Delta H\) and \(\Delta S\) are @[email protected] and @[email protected] of reaction, respectively.
