@ -24,13 +24,15 @@ celestite; following diffusion of $BaCl_2$ celestite dissolution
occurs Dissolution of celestite and the successive release of
$SO_4^{2-}$ into solution causes barite to precipitate:
```\mathrm{Ba}^{2+}_{\mathrm{(aq)}} + \mathrm{SrSO}_{4, \mathrm{(s)}} \rightarrow \mathrm{BaSO}_{4,\mathrm{(s)}} + \mathrm{Sr}^{2+}_{\mathrm{(s)}}```

$ \mathrm{Ba}^{2+}_{\mathrm{(aq)}} + \mathrm{SrSO}_{4, \mathrm{(s)}} \rightarrow \mathrm{BaSO}_{4,\mathrm{(s)}} + \mathrm{Sr}^{2+}_{\mathrm{(s)}} $
#+end_src
Reaction rates are calculated using a general kinetics rate law for
both dissolution and precipitation based on transition state
theory:
```\frac{\mathrm{d}m_{m}}{\mathrm{d}t} = -\mathrm{SA}_m k_{\mathrm{r},m} (1-\mathrm{SR}_{m})```
$ \frac{\mathrm{d}m_{m}}{\mathrm{d}t} = -\mathrm{SA}_m k_{\mathrm{r},m} (1-\mathrm{SR}_{m})$
where $\mathrm{d}m\,(\mathrm{mol/s})$ is the rate of a mineral phase
