### Solids/Liquids

For the rate of the reaction, k[a][b], what happens if either a or b is a solid or liquid. Is it like the equilibrium constant where a product/reactant in a solid or gas phase is negligible?

because rate is measured in change in concentration versus time only things that have concentrations can change it, so only gases and aqueous substances are included i believe.

I think the "concentration" of solids and liquids is not included in the rate law.

Because solids and liquids do not have a concentration, they are not included in the rate law.
