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

Kc = Kp/RT = Km . RT/P
Kc = Kp = Km
Kc = Kp . RT = Km . RT/p
None of these

Mass Transfer
In case of steam distillation, the steam leaving the liquid is not completely saturated with distillate vapour, because

Saturated steam is used for steam distillation
Temperature is less
Mixing of steam with the material being vaporised is not so intimate as to result in equilibrium condition
Total pressure is less
