Consider the following equilibrium: N₂O4 (8)2NO₂ (8) AG=5.4 kJ Now suppose a reaction vessel is filled with 1.32 atm of dinitrogen tetroxide (N₂O4) at 322. °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 rise by adding NO₂? If you said the tendency can be reversed in the second question, calculate the minimum pressure of NO₂ needed to reverse it. Round your answer to 2 significant digits. rise O fall O yes O no atm x10 X

Question
Consider the following equilibrium:
N₂O4 (g) 2NO₂ (g)
AG = 5.4 kJ
Now suppose a reaction vessel is filled with 1.32 atm of dinitrogen tetroxide (N₂O4) at 322. °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 NO₂ needed to reverse it.
Round your answer to 2 significant digits.
