Consider the following equilibrium: 2NH, (g) N₂ (g)+3H2(g) = AG = 34. KJ Now suppose a reaction vessel is filled with 7.72 atm of ammonia (NH3) a system: and 2.59 atm of nitrogen (N2) at 139. °C. Answer the following questions about this rise x10 fall Under these conditions, will the pressure of N2 tend to rise or fall? Is it possible to reverse this tendency by adding H₂? In other words, if you said the pressure of N2 will tend to rise, can that be changed to a tendency to fall by adding H₂? Similarly, if you said the pressure of N2 will tend to fall, can that be changed to a tendency to rise by adding H₂?

Question
Consider the following equilibrium:
2NH3 (g) N2 (g)+3H2(g)
AGº = 34. kJ
Now suppose a reaction vessel is filled with 7.72 atm of ammonia (NH3) and 2.59 atm of nitrogen (N2) at 139. °C. Answer the following questions about this
system:
rise
Under these conditions, will the pressure of N2 tend to rise or fall?
fall
OO
Is it possible to reverse this tendency by adding H2?
In other words, if you said the pressure of N2 will tend to rise, can that be
changed to a tendency to fall by adding H₂? Similarly, if you said the
pressure of N2 will tend to fall, can that be changed to a tendency to rise
by adding H₂?
If you said the tendency can be reversed in the second question, calculate
the minimum pressure of H₂ needed to reverse it.
Round your answer to 2 significant digits.
yes
no
