SiH does not alter any significantly because of the reaction, the kinetics of this surface reaction can be expected to be of first order with respect to the salt concentration; i.e. for HAuCl4, it is , where     A is a constant. To understand how  would vary with   Au , we consider the results obtained from experiments carried out previously with aqEth, in which  scaled linearly with Ethanol concentration, Eth C (Fig. ). Since such dependence was essentially born out of alteration in the solid-liquid interfacial energy, for the case of generation of nano-particles too,  was expected to scale linearly with the surface concentration of the AuNPs,
