Solids and Liquids are not included in the Equilibrium Constant equation so in the class example Ca(OH)2 (s) ---> Ca2+ (aq) + 2OH- (aq), if we looked at the reverse reaction, would it just be the inverse? In chemical equilibrium, does this mean that this chemical equation will not change in the slightest?
If you calculate K (forwards) for the forward reaction, the backwards reaction has a K (backwards) value that is the inverse of the K (forwards). This is because you calculate using a ratio of the concentration of reactants to the power of stoichiometric coefficients and products to the power of their stoichiometric coefficients. These values do not change when switching a reaction. The only thing that changes is the reactants become products and products become reactants, which, if you look at the K equation, works out to be the inverse.
With regards to what you asked about the equation changing, it literally will not change at all. You pretty much just switch the sides the reactants and products are on and that's it, and as mentioned above, the new equilibrium constant is just the inverse of the old one.
