Calculate how the equilibrium will shift

Question

1. Determine the Ke for the following (equilibrium concentrations given below substances)

a.      4NH₃ (g)    +     3 O₂(g)     ↔     2N₂ (g)     +    6 H₂O (g)    +     heat

         [0.010]         [0.10]               [0.0794]         [0.10]

b.      N₂(g)     +     3H₂ (g)    +    heat     ↔     2NH₃ (g)

         [0.103]       [0.240]                     [0.0114]

c.      H₂(g)     +    Cl₂ (g)    ↔     2 HCl(g)     +     heat

         [0.21]                  [0.22]                      [0.784]

2. For all three of the equilibrium in the problem 1

a. Calculate how much Ke is affected by an decrease in temperature?

b. When pressure is increased, calculate how the equilibrium will shift?

c. Calculate how the equilibrium will shift when the concentration of the underlined substance is increased.

d. Calculate how the equilibrium will shift when the temperature is increased.
