... in the diffusion coefficient results because of the slow reaction rate of dolomite. Moreover, HCl/dolomite reaction was mass transfer limited at low disk rotational speeds and surface reaction limited at high disk rotational speeds. In addition, diffusion coefficient was significantly affected by rock porosity due...
