If Raoult's law is obeyed, then changing the feed composition would effect Neither the product composition nor the fraction vaporised The fraction vaporised but not the product composition The product composition but not the fraction vaporised The product composition as well as the fraction vaporised Neither the product composition nor the fraction vaporised The fraction vaporised but not the product composition The product composition but not the fraction vaporised The product composition as well as the fraction vaporised ANSWER DOWNLOAD EXAMIANS APP
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/RT = Km . RT/P None of these Kc = Kp = Km Kc = Kp . RT = Km . RT/p Kc = Kp/RT = Km . RT/P None of these Kc = Kp = Km ANSWER DOWNLOAD EXAMIANS APP
