Consider the following equilibrium: 2NH, (g) – N, (g) + 3H, (g) AG°=34. kJ Now suppose a reaction vessel is filled with 4.89 atm of ammonia (NH,) and 5.72 atm of nitrogen (N,) at 847. °C. Answer the following questions about this system: O rise Under these conditions, will the pressure of NH, tend to rise or fall? fall Is it possible to reverse this tendency by adding H,? In other words, if you said the pressure of NH, will tend to rise, can that O yes be changed to a tendency to fall by adding H,? Similarly, if you said the no pressure of NH, will tend to fall, can that be changed to a tendency to rise by adding H,? If you said the tendency can be reversed in the second question, calculate the minimum pressure of H, needed to reverse it. atm Round your answer to 2 significant digits.

Consider the following equilibrium: 2NH, (g) - N, (g)+3H, (g) AG° = 34. kJ Now suppose a reaction vessel is filled with 4.89 atm of ammonia (NH,) and 5.72 atm of nitrogen (N,) at 847. °C. Answer the following questions about this system: rise Under these conditions, will the pressure of NH, tend to rise or fall? x10 fall Is it possible to reverse this tendency by adding H,? In other words, if you said the pressure of NH, will tend to rise, can that 3 yes be changed to a tendency to fall by adding H,? Similarly, if you said the no pressure of NH, will tend to fall, can that be changed to a tendency to 3 rise by adding H,? If you said the tendency can be reversed in the second question, calculate the minimum pressure of H, needed to reverse it. 2. atm Round your answer to 2 significant digits.
