Question
Chapter 15, Problem 15.6QAP
Interpretation Introduction
Interpretation:
The major reasons for more usage of molecular fluorescence spectrometry in comparison to molecular phosphorescence spectrometry should be discussed.
Concept introduction:
Phosphorescence spectrometry is closely related to fluorescence. The transition from excited to ground state takes time in this type of photoluminescence process.

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.
