1, Calculate Ke for the following (equilibrium concentrations given below substances)

a) PCl5 (g) + heat ↔ PCl3 (g) + Cl2 (g)
[0.105] [0.219] [0.219]

b) 2 SO2 (g) + O2 (g) ↔ 2 SO3 (g) + heat
[0.0500] [0.0500] 0.103]

c) CO2 (g) + H2 (g) ↔ CO (g) + H2O (g)+ heat
[0.245] [0.245] 0.575] [0.575]

2. For each of the equilibria in problem #1 predict (1) how Ke is affected by an increase in temperature, (2) predict how the equilibrium will shift when pressure is decreased, (3) predict how the equilibrium will shift when the concentration of the underlined substance is increased, and (4) predict how the equilibrium will shift when the temperature is decreased.
