When forming rate laws do we include solids and liquids?

When writing rate laws do we include solids and liquids in the rate law expression?

[Shawn Patel 1I]

Hey,
Most of the time we would not include solids and liquids, only gases and aqueous solutions. Water can be included if it is part of the reaction.

[Manasvi Paudel 1A]

The concentration of solids and liquids does not affect the reactant amount at equilibrium so they are disregarded.

[Cassandra Mullen 1E]

Just like when writing equilibrium constant expressions, the concentration of solids and liquids are essentially constant so they can be omitted in the rate law expression.
