Figure : Bimolecular surface reaction rate coefficient k SLR (symbols) plotted as a function of droplet ionic strength prior reaction and the fit (lines) with eq 2. These values of k SLR were retrieved from fitting the kinetics data of binary STS with the KM-SUB model simulation results where the effect of interfacial ion depletion is (a) not included (θ ss = 0) or (b) included (θ ss > 0), and the corresponding input parameters are provided in Tables and, respectively.
