for writing the equilibrium expression, what if there's nothing on the top?
cuz it's like:
So3(g) + H2O(g) -> H2SO4 (l)
and it tells me to write the equilibrium expression..

If there's nothing on top (or the bottom) of an equilibrium constant, you put a 1. For the equation you're talking about, the eq. constant is:
K = 1 /[SO3][H20]
(For those who are wondering, the H2SO4 isn't usually included for an equation like this since it's in the liquid phase in this reaction. If it had been in the aqueous phase, it would generally be included.)

equm. const is equal to ratio betwwen the product of concentration of the products to the product of the concentration of the reactants. if they have the numbers in front of the SO3, H2O, H2SO4 then you should put that number as power to the concentration term.

answer is K=[H2SO4]/[SO3][H2O]
