Average solute concentration normalized by the external bath concentration, ${\widehat{c}}_{\mathit{\text{avg}}}^f\left(\widehat{t}\right)/{\kappa }^f{\widehat{c}}^{f^{*}}$, as a function of time, for various choices of governing parameters (R_g = 100, R_d = 0.1, ε₀ = −0.20, and f̂ = 0; R_g = 100, R_d = 0.1, ε₀ = −0.20, and f̂ = 10; R_g = 100, R_d = 0.1, ε₀ = −0.20, and 100).
