All products are solids

Postby Parth Mungra » Wed Jan 23, 2019 10:06 am

If you are trying to write an equilibrium constant for a rxn where all the products are solids, would this mean that the entire reaction has no equilibrium constant? Or would it be 1/[r]?

I don't think that solids can be in equilibrium? The molar concentration of a solid does not change, thus they are just represented as 1 in the equilibrium constant.

Equilibrium constant would be equal to
1/[r] — if concentrations are given or reactants are aqeous
1/(Pr) — if reactants are gases

Theoretically yes?

But I agree with the comment above. It's unlikely something like this would come out.
