Consider the following equilibrium: 2NH3 (g) = N2 (g)+ 3H, (g) AG = 34. kJ Now suppose a reaction vessel is filled with 7.65 atm of ammonia (NH,) and 0.884 atm of hydrogen (H,) at 600. °C. Answer the following questions about this system: rise Under these conditions, will the pressure of NH, tend to rise or fall? O fall Is it possible to reverse this tendency by adding N,? 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 N,? Similarly, if you said the O no pressure of NH, will tend to fall, can that be changed to a tendency to rise by adding N,? If you said the tendency can be reversed in the second question, calculate the minimum pressure of N, needed to reverse it. ||atm Round your answer to 2 significant digits.

Which of the following is correct about the reaction? 1.The reaction is at equilibrium. 2.The reaction is not at equilibrium, it will shift to the left to reach equilibrium. 3.the reaction is not at equilibrium it will shift to the right to reach equilibrium.
Consider the following equilibrium: N,0, (g) = 2NO, (3) AG' = 5.4 kJ Now suppose a reaction vessel is filled with 0.496 atm of nitrogen dioxide (NO,) at 137. °C. Answer the following questions about this system: O rise Under these conditions, will the pressure of NO, tend to rise or fall? O fall Is it possible to reverse this tendency by adding N,O,? In other words, if you said the pressure of NO, will tend to rise, can that O yes be changed to a tendency to fall by adding N,04? Similarly, if you said O no the pressure of NO, will tend to fall, can that be changed to a tendency to rise by adding N,0,? If you said the tendency can be reversed in the second question, calculate the minimum pressure of N,0, needed to reverse it. O atm Round your answer to 2 significant digits.
