Chemical Engineering - Mass Transfer - Discussion

The relation among various mass transfer co-efficients (M.T.C) for ideal gases is given by (where, K_c & K_m are M.T.C. for equimolar counter diffusion with concentration & mole fraction respectively as the driving force. and, K_p = M.T.C. for diffusion of a gas through a stagnant inert gas with pressure as driving force.)
