Definition

A proportionality constant Kc that relates a species' mass flux J (mass or molar) to a driving concentration difference at an interface or within a phase, commonly expressed as J = Kc·(C_bulk − C_interface) or J = Kc·ΔC; Kc has units of length/time and encapsulates transport resistance determined by diffusivity, flow field and interfacial boundary layer thickness.
