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 Kc = Kp/RT = Km . RT/P Kc = Kp = Km Kc = Kp . RT = Km . RT/p None of these ANSWER DOWNLOAD EXAMIANS APP
