Mass Transfer Pick out the wrong statement. Raoult's law does not apply, when the Chemical combination or molecular association between unlike molecules takes place in the formation of solution Attractive forces between like and unlike molecules in the solution are approximately equal Component molecules are nonpolar Size of component molecules are not equal Chemical combination or molecular association between unlike molecules takes place in the formation of solution Attractive forces between like and unlike molecules in the solution are approximately equal Component molecules are nonpolar Size of component molecules are not equal ANSWER DOWNLOAD EXAMIANS APP
Mass Transfer Though, theoretically the adsorption & desorption isotherms is expected to coincide but sometimes at least a part of the isotherms does not coincide and this phenomenon is known as adsorption hysterisis. In such cases, the desorption equilibrium pressure is __________ that obtained for adsorption.
