Mole Ratio with a Solid

Postby sophiebillings1E » Fri Jan 11, 2019 4:11 pm

In the example,
B(g) + C(g)<-->A(s)
If volume is decreased, would I say the reaction favors products because mole ratio is (2:0)?

You are correct. Using the quick method, solids don't exert pressure, so decreasing the volume (and therefore increasing the pressure/concentrations of reactants) would cause the reaction to favor the formation of products by Le Chatelier's principle.

Is it the same case for liquids as it is for solids?

Yes, it should be the same case in this example, as liquid don't contribute much towards pressure like solids.
