Fig. 4: Log of the experimental dissolution rates for
various PCO2 (listed by the symbols on the curve and by the first row in the inset) as
function of the log of the rotating speed in rpm.
All curves exhibit straight lines. Therefore a relation Rµ Wn is valid. The corresponding
values of n are listed in the second row in the inset. Open symbols refer to a calcium
concentration of 3x10-4 mol/l, closed symbols to a concentration of 1x10-3 mol/l
respectively.
