2. Explain how each of the following factors affects the amount of hydrogen gas present in an equilibrium mixture in the following reaction: 3 Fe(s) + 4 H,O(g) Fe;O4(s) + 4 H2(g) AH = - 150KJ 1) addition of a catalyst e) decreasing the volume
Consider the following equilibrium: 2NO, (g) = N,04 (g) AG° = - 5.4 kJ Now suppose a reaction vessel is filled with 8.21 atm of dinitrogen tetroxide (N,0,a) at 588. °C. Answer the following questions about this system: rise Under these conditions, will the pressure of N,0, tend to rise or fall? '2 fall Is it possible to reverse this tendency by adding NO,? In other words, if you said the pressure of N,O, will tend to rise, can that 4. yes be changed to a tendency to fall by adding N0,? Similarly, if you said the no pressure of N,04 will tend to fall, can that be changed to a tendency to rise by adding NO,? If you said the tendency can be reversed in the second question, calculate the minimum pressure of NO, needed to reverse it. atm Round your answer to 2 significant digits. O O
