Figure 8

Logarithm of the steady-state dissolution rates as a function of $\log \left(\frac{a_{H^{+}}^2}{a_{M{g}^{2+}}}\right)$. The symbols represent experimentally determined rates obtained at different temperatures. The data were fitted with an ion exchange model and the fitted rates are shown in the figure by colored lines. The same color is used for the experimentally determined and fitted rates (see text for details).
