Textbook Question
Chapter FRP, Problem 24P
Dehydrohalogenation of meso-1, 2-dibromo-1, 2-diphenylethane by the action of sodium ethoxide in ethanol yields (E)-1-bromo-1-2-diphenylechene. Similar dehydrohalogenation of either enantiomer of 1, 2-dibromo-1, 2-diphenylechane yields (Z)-1-bromo-1, 2-diphenylethene. Provide an explanation for the results.

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.
