Consider the following equilibrium: N2 (g)+3H2(g)2NH, (g) AGº = -34. KJ Now suppose a reaction vessel is filled with 2.15 atm of nitrogen (N2) and 2.19 atm of ammonia (NH3) at 236. °C. Answer the following questions about th system: Under these conditions, will the pressure of NH3 tend to rise or fall? rise 09 x10 fall Is it possible to reverse this tendency by adding H₂? In other words, if you said the pressure of NH3 will tend to rise, can that be changed to a tendency to fall by adding H2? Similarly, if you said the pressure of NH3 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 ☐ atm

Question
Consider the following equilibrium:
N2 (g)+3H2(g)2NH3 (g) AG = -34. KJ
Now suppose a reaction vessel is filled with 2.15 atm of nitrogen (N2) and 2.19 atm of ammonia (NH3) at 236. °C. Answer the following questions about this
system:
Under these conditions, will the pressure of NH3 tend to rise or fall?
rise
☐ x10
fall
оо
Is it possible to reverse this tendency by adding H₂?
In other words, if you said the pressure of NH3 will tend to rise, can that
be changed to a tendency to fall by adding H2? Similarly, if you said the
pressure of NH3 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
☐ at
atm
