Question
Chapter A1, Problem A1.7QAP
Interpretation Introduction
Interpretation:
The relative error in the results due to this systematic error if the sample taken for analysis weighed
Concept introduction:
Solubility is the property of the substance by virtue of which a substance is able to dissolve with other substance which can be of the same state or can be in a different state. Solubility loss depends on the properties of the two substances to be mixed including solubility.

Using reaction free energy to predict equilibrium composition
Consider the following equilibrium:
2NO2 (g) = N2O4(g)
AGº = -5.4 kJ
Now suppose a reaction vessel is filled with 4.53 atm of dinitrogen tetroxide (N2O4) at 279. °C. Answer the following questions about this system:
Under these conditions, will the pressure of N2O4 tend to rise or fall?
Is it possible to reverse this tendency by adding NO2?
In other words, if you said the pressure of N2O4 will tend to rise, can that
be changed to a tendency to fall by adding NO2? Similarly, if you said the
pressure of N2O4 will tend to fall, can that be changed to a tendency to
'2'
rise by adding NO2?
If you said the tendency can be reversed in the second question, calculate
the minimum pressure of NO 2 needed to reverse it.
Round your answer to 2 significant digits.
