Just for a simplicity consider a pure substance B. By analogy with the migration of a high-angle grain boundary the net flux of B across the interface will produce an interface velocity v given by____ (Interface mobility is given as M, Molar volume V, and the driving force is given as Δμ)
Just for a simplicity consider a pure substance B. By analogy with the migration of a high-angle grain boundary the net flux of B across the interface will produce an interface velocity v given by____ (Interface mobility is given as M, Molar volume V, and the driving force is given as Δμ) Correct Answer MΔμ/V
The interface velocity is the product of the interface mobility and the driving force per unit molar volume, so in this case the interface mobility is given as M, Molar volume V, and the driving force is given as Δμ so the required velocity is MΔμ/V.
