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 Size of component molecules are not equal Attractive forces between like and unlike molecules in the solution are approximately equal Component molecules are nonpolar Chemical combination or molecular association between unlike molecules takes place in the formation of solution Size of component molecules are not equal Attractive forces between like and unlike molecules in the solution are approximately equal Component molecules are nonpolar ANSWER DOWNLOAD EXAMIANS APP
