16 points: Consider the following equilibrium reaction:

4NH₃ (g) + 5O₂ (g) 4NO (g) + 6H₂O (g) H = 904.4 kJ/mol

How does each of the following affect the amount of NO(g) present to re-establish equilibrium? Answer increase, decrease, or no change.

Adding O₂ (g): _____________

Decrease temperature: ____________

Increase the pressure: _____________

Adding liquid water: _______________

Adding a catalyst:

Circle true or false: This reaction is exothermic, so it must be fast.

Circle true or false: Adding a catalyst to this reaction will decrease the H.

Circle true or false: The reverse reaction as written above is endothermic.
