CHEMISTRY PROBLEM!? NEED URGENT HELP!?

Question: Write the equilibrium constant for the following reversible reaction.

H2SO4 (aq) + 8HI (aq) <--> H2S (g) + 4I2(s) + 4H2O (I)

2 SO3 (g) <--> 2 SO2 (g) + O2 (g)

CO (g) + H2O (g) <--> CO2 (g) + H2 (g)

I don't understand the question. Is it asking for the equilibrium EXPRESSION? I asked my teacher and he said he wanted me to set up the equation only. I don't need to calculate anything. Help?!
