Changing the amount of a solid reactant or product in an equilibrium reaction will not affect the amounts of the other reactants and products present at equilibrium.

According to Le Chatelier's principle, if a system at equilibrium is subjected to a change in conditions (such as a change in concentration), the system will adjust to counteract the change and maintain equilibrium. If the concentration of one solid reactant or product changes, the equilibrium position will shift to either produce more or less of that solid, without affecting the concentrations of the other reactants and products. However, this principle only applies to solids, as changing the concentration of a gas or dissolved substance can affect the concentrations of other substances in the equilibrium reaction.
