The equilibrium constant (K) is defined for a specific reaction at a given temperature and is indeed independent of the concentrations of reactants and products at equilibrium. However, when the entire equilibrium expression is multiplied by a factor, the equilibrium constant itself does not change; rather, the concentrations of the species involved will adjust to maintain the equilibrium condition. This discussion clarifies that the apparent contradiction arises from a misunderstanding of how equilibrium constants function in relation to concentration changes.
