Question
Chapter 4, Problem 4A.3DQ
Interpretation Introduction
Interpretation:
The reason due to which four phases cannot be in equilibrium in one component system is to be stated.
Concept Introduction:
One component system is a system involving only one pure substance in different phases. The system is defined by a set of variables and the minimum number of variable used to define the system is called its degree of freedom. The degree of freedom is a positive quantity and cannot be negative.

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.
