The trisodium phosphate ( Na 3 PO 4 ) ideality should be identified. Concept Introduction : Solution : The solution is simple homogenies mixture composed of two or more substance; solute is a substance dissolved in another substance it well known as solvent. Ideal solutions : The solution in which interactions between molecules of the components does not differ from the interactions between the molecules of each component. For example the ideal solutions that conforms exactly to Raoult’s law it compare to the activity and activity co-efficient. Non Ideal gas : The solutions whose properties are generally not very predictable of account of the intermolecular forces between the molecules. This solution cannot be dealt with through Raoult’s law; this law is strictly for ideal solutions only. Raoult’s law : This state that the partial vapor pressure of each component of an ideal mixture of liquids is equal to the vapor pressure of the pure component multiplied by its mole fractions in the mixture. The negative deviations from Raoult’s law arise when forces between the partials in the mixture are stronger than the mean of the force between the partials in the pure liquids.

Na3PO4) ideality should be identified.
Concept Introduction:
Solution: The solution is simple homogenies mixture composed of two or more substance; solute is a substance dissolved in another substance it well known as solvent.
Ideal solutions: The solution in which interactions between molecules of the components does not differ from the interactions between the molecules of each component. For example the ideal solutions that conforms exactly to Raoult’s law it compare to the activity and activity co-efficient.
Non Ideal gas: The solutions whose properties are generally not very predictable of account of the intermolecular forces between the molecules. This solution cannot be dealt with through Raoult’s law; this law is strictly for ideal solutions only.
Raoult’s law: This state that the partial vapor pressure of each component of an ideal mixture of liquids is equal to the vapor pressure of the pure component multiplied by its mole fractions in the mixture. The negative deviations from Raoult’s law arise when forces between the partials in the mixture are stronger than the mean of the force between the partials in the pure liquids.
The table includes macrostates characterized by 4 energy levels (&) that are
equally spaced but with different degrees of occupation.
a) Calculate the energy of all the macrostates (in joules). See if they all have
the same energy and number of particles.
b) Calculate the macrostate that is most likely to exist. For this macrostate,
show that the population of the levels is consistent with the Boltzmann
distribution.

In an experiment, the viscosity of water was measured at different
temperatures and the table was constructed from the data obtained.
a) Calculate the activation energy of viscous flow (kJ/mol).
b) Calculate the viscosity at 30°C.
