Answer #1

1) Pure solids and liquids are included in the equilibrium constant expression.

---> False. Pure solids and liquids are not included in equillibrium constant expression. Because at equillibrium, the reactant amount is not affected.

2) All solids and liquids are included in the equilibrium constant expression.

---> False.

3) Pure solids and liquids are not included in the equilibrium constant expression.

---> True. Because the pure solids and liquids do not affect the amount of reatant at the equillibrium, so, they are not included in the equillibrium constant expression.
