Mass Transfer Pick out the wrong statement. Raoult's law does not apply, when the Size of component molecules are not equal Component molecules are nonpolar 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 Size of component molecules are not equal Component molecules are nonpolar 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 ANSWER DOWNLOAD EXAMIANS APP
Mass Transfer One mole feed of a binary mixture of a given composition is flash vaporised at a fixed P and T. If Raoult's law is obeyed, then changing the feed composition would effect The fraction vaporised but not the product composition The product composition as well as the fraction vaporised Neither the product composition nor the fraction vaporised The product composition but not the fraction vaporised The fraction vaporised but not the product composition The product composition as well as the fraction vaporised Neither the product composition nor the fraction vaporised The product composition but not the fraction vaporised ANSWER DOWNLOAD EXAMIANS APP
