Logarithm of the steady-state dissolution rates as a function of $\log \left(\frac{a_{H^{+}}^4}{a_{C{a}^{2+}}{a}_{M{g}^{2+}}}\right)$. The experiments are conducted at 150°C and in situ pH of 7.5. The symbols represent different stacked experiments: squares and circles represent experiments initiated at far from equilibrium conditions, whereas, the symbols represented by diamonds were started at close to equilibrium conditions. The data points shown inside the oval were initiated with Ca in the input solution and were started at close to equilibrium conditions.
