How Do You Write the Reaction Quotient Qc for This Reaction?

[MG5]

Can't figure this one out. Here's the problem.

Solid molybdenum (VI) oxide reacts with gaseous xenon difluoride to form liquid molybdenum(VI) fluoride, xenon gas, and oxygen gas. Write the Q_c for this reaction.

I know Q_c is products over reactants and pure liquids and solids are not included.

So this is what I came up with. Its wrong though.

Q_c= [XeF₂]³ / [Xe]³ [O₂]

Any help would be great. Thanks.

1. What is the balanced reaction equation?

2. If it is products over reactants, why do you have XeF₂ - a reactant - in the numerator?
