The pressure on each of the following systems is increased by decreasing the volume of the container. Explain whether each system would shift in the forward direction, the reverse direction, or stay the same.

a.	2 SO2 (g) + O2 (g) 2 SO3 (g)
b.	H2 (g) + I2 (g) 2 HI(g)
c.	CaCO3 (s) CaO(s) + CO2 (g)
d.	AgCl(s) Ag1+(aq) + Cl1-(aq)

List three ways that the following equilibrium reaction could be forced to shift to the right:

2 NO_{2 (g)} 2 NO_(g) + O_{2 (g)}

Given the following equilibrium reaction:

2 C_(s) + O_{2 (g)} 2 CO_(g)

what will be the effect of the following disturbances to the system:
