 $SO_4^{2-}$ into solution causes barite to precipitate:

 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
