Homework Help: chemistry

balance: SO2(g)+O2(g)------->SO3(g)
the concentration of SO2 and O2 are determined to be [0.06] and [0.03] if the following reaction has a Kc of 3.6x10^2, what is the concentration of SO3????

any work would be much appreciated thank you!!

............2SO2 + O2 ==> 2SO3
Is that [0.06] and [0.03] at equilibrium or is that how they started. If at equilibrium, then
Kc = (SO3)^2/(SO2)^2(O2)
You know Kc, SO2 and O2, solve for SO3 which is the only unknown in the equation.
