Question

1) For the following reaction:

SO2Cl2(g)<-> SO2(g) + Cl2 (g)   Kp=2.91x10^3 at 298K

In the reaction at equilibrium, the partial pressure of SO2 is 137 torr and that of CL2 is 285 torr. The partial pressure of SO2Cl2 is [x]torr.

2) For the following reaction:NH4HS(s)<->NH3(g) + H2S (g)     Kc=8.5x10^-3

At any given point the reaction mixture has solid NH4HS, NH3 at 0.166M and H2S at 0.166M.

a) Is the reaction at equilibrium?

b)Will more of the solid form, or will some of the existing solid decompose?

3) Consider the following reaction: CH3OH (g) <-> CO (g) + 2H2 (g)     deltaH=+90.7 kJ/mol

Select what disturbances you can do to shift the reaction to the right (check all that apply)

• Decrease the temperature
• Increase the temperature
• Add CO
• Remove CH3OH
• Expand the volume
• Remove H2
• Add CH3OH
• Decrease the volume
