Consider the following equilibrium: 2NH₂ (g) N₂(g) + 3H₂(g) AG = 34. KJ Now suppose a reaction vessel is filled with 2.49 atm of ammonia (NH3) and 4.30 atm of nitrogen (N₂) at 973. °C. Answer the following questions about this system: Under these conditions, will the pressure of N, tend to rise or fall? Is it possible to reverse this tendency by adding H₂? In other words, if you said the pressure of N, will tend to rise, can that be changed to a tendency to fall by adding H₂? Similarly, if you said the pressure of N, 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. O rise O fall O yes O no x10 X
