Stoichiometry In case of a ternery system involving two liquid components and a solute, the ratio of the concentration of the solute in the two phases at equilibrium is called the distribution co-efficient. The distribution co-efficient depends upon the Temperature Solute concentration Neither A nor B Both A & B Temperature Solute concentration Neither A nor B Both A & B ANSWER DOWNLOAD EXAMIANS APP
Stoichiometry Assume that benzene is insoluble in water. The normal boiling points of benzene and water are 80.1 and 100°C respectively. At a pressure of 1 atm, the boiling point of a mixture of benzene and water is 100°C 80.1°C Greater than 80.1°C but less than 100°C Less than 80.1°C 100°C 80.1°C Greater than 80.1°C but less than 100°C Less than 80.1°C ANSWER DOWNLOAD EXAMIANS APP
Stoichiometry The vapor pressure of the solvent decreased by 10 mm Hg, when a non-volatile solute was added to the solvent. The mole fraction of the solute in the solution is 0.2. What should be the mole fraction of the solvent, if the decrease in vapor pressure of the solvent is required to be 20 mm Hg.? 0.2 0.6 0.4 0.1 0.2 0.6 0.4 0.1 ANSWER DOWNLOAD EXAMIANS APP
Stoichiometry Unrestrained expansion of an ideal gas does not result in its cooling due to the reason that the gas molecules Are above the inversion temperature Do work equal to loss in kinetic energy Do not exert attractive force on each other Do not lose energy on collision Are above the inversion temperature Do work equal to loss in kinetic energy Do not exert attractive force on each other Do not lose energy on collision ANSWER DOWNLOAD EXAMIANS APP
