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

Mass Transfer In case of physical adsorption, the difference between heat of adsorption and heat of normal condensation is Zero Called integral heat of adsorption Equal to the heat of wetting Equal to the heat of formation of surface compound Zero Called integral heat of adsorption Equal to the heat of wetting Equal to the heat of formation of surface compound ANSWER DOWNLOAD EXAMIANS APP
Mass Transfer In a moderately sized packed absorption tower, channeling (which is most severe with stacked packings) can be minimised by taking the ratio of tower diameter to packing diameter < 6:1 > 8:1 > 4 :1 < 8 : 1 < 6:1 > 8:1 > 4 :1 < 8 : 1 ANSWER DOWNLOAD EXAMIANS APP
Mass Transfer On moving the feed line (q-line) from saturated liquid feed (vertical position) to saturated vapor feed (horizontal feed), if the slope of both the operating lines are to be increased, then it will result in Increased reboiler load Increased reflux ratio None of these Greater degree of separation with a fixed number of trays Increased reboiler load Increased reflux ratio None of these Greater degree of separation with a fixed number of trays ANSWER DOWNLOAD EXAMIANS APP
