Mass Transfer Pick out the wrong statement. Raoult's law does not apply, when the Size of component molecules are not equal Attractive forces between like and unlike molecules in the solution are approximately equal Chemical combination or molecular association between unlike molecules takes place in the formation of solution Component molecules are nonpolar Size of component molecules are not equal Attractive forces between like and unlike molecules in the solution are approximately equal Chemical combination or molecular association between unlike molecules takes place in the formation of solution Component molecules are nonpolar ANSWER DOWNLOAD EXAMIANS APP
Mass Transfer The individual mass transfer co-efficients (moles/m² . s) for absorption of a solute from a gas mixture into a liquid solvent are, KL = 4.5 and KG = 1.5.
