1. The Kc for the following reaction is low.
  X ↔ Y
It can be deduced that the _________ is low.

2. Consider the following equilibrium :
N2(g) + 3H2(g) ↔ 2NH3(g) ΔH = -92kJ
Which favours less NH3 at a greater rate?

3. The following chemical equilibrium is established at a constant temperature in a closed container:
4NH3(g) + 5O2(g) ↔ 4NO(g) + 6H2O(g) (ΔH < 0) . Which set of conditions will both favour a reverse shift?

4. Study the ffg reaction which is in equilibrium.
NaNO3(s) ↔ Na+(aq) + NO3- (aq)
A few drops of concentrated nitric acid added to the above equilibrium mixture. (Assume no significant change to V or T).
Which of the following best describes the possible change in the equilibrium?

5. The Kc for a reaction at 3000C is 0,001. This means that the reaction:
