In case of vapor-liquid equilibria, which of the following does not account for gas phase deviation from ideality?
-
If the pressure of a gas is reduced to half & its absolute temperature is doubled, then the volume of the gas will

A solution having a pH value of 5 is less acidic than the one having a pH value of 2 by a factor of
-
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. ?
