Do I use mole ratio when solids are in equation to determine which way it will favor.
Example,
A(s) <--> B(g) + C(g)
If volume is decreased, would I say the reaction favors reactants because mole ratio is (0:2)

Re: mole ratio with solids
yes, just as when you're calculating eq constants, change in pressure/conc doesn't impact solids or gasses, thus you only take into account the gasses that are compressed by increase in pressure/decrease in volume. (moving it to the left after you calculate Q)

I would say that if the volume is decreased, it means the molarity of the products goes up, so Q goes up. If Q > K, then the reaction shifts left/favors reactants.
