Consider the following equilibrium: 2NO₂ (g) N₂O(g) AG=-5.4 kJ Now suppose a reaction vessel is filled with 0.202 atm of nitrogen dioxide (NO₂) at 504. °C. Under these conditions, will the pressure of NO₂ tend to rise or fall? Is it possible to reverse this tendency by adding N₂O4? In other words, if you said the pressure of NO₂ will tend to rise, can that be changed to a tendency to fall by adding N₂O4? Similarly, if you said the pressure of NO₂ will tend to fall, can that be changed to a tendency to rise fall yes no

Question
Transcribed Image Text:Consider the following equilibrium:
2NO₂(g) → N₂O4 (g)
AG = -5.4 kJ
Now suppose a reaction vessel is filled with 0.202 atm of nitrogen dioxide (NO₂) at 504. °C. A
Under these conditions, will the pressure of NO₂ tend to rise or fall?
Is it possible to reverse this tendency by adding N₂O4?
In other words, if you said the pressure of NO₂ will tend to rise, can that
be changed to a tendency to fall by adding N₂O4? Similarly, if you said
the pressure of NO₂ will tend to fall, can that be changed to a tendency to
rise by adding N₂O4?
If you said the tendency can be reversed in the second question, calculate
the minimum pressure of N₂O needed to reverse it.
