Which of the following expressions best defines the permeability coefficient, kp, for a non ionizable compound dissolved in a vehicle (v) in contact with a membrane (m)?
A. kp = DKmv / h Note: h is the membrane thickness (called l in the slides)
B. 1 / kp = 1 / kaq + 1 / (klip + kpol)
C. kp = Jss / ΔCext
D. None of the above is satisfactory.
