The equilibrium constant of a reversible chemical reaction at a given temperature

Explanation

Option C is correct.The equilibrium constant of a reversible chemical reaction at a given temperature does not depend on the initial concentration of the reactants. It is a characteristic of the reaction and is independent of the initial concentrations of the reactants. The equilibrium constant is a measure of the relative rates of the forward and backward reactions at equilibrium. It is a constant for a particular reaction at a given temperature. A large equilibrium constant means that the forward reaction is favored over the backward reaction. A small equilibrium constant means that the backward reaction is favored over the forward reaction. The initial concentrations of the reactants do not affect the equilibrium constant. The equilibrium constant is determined by the thermodynamic properties of the reactants and products. For example, the equilibrium constant for the reaction of hydrogen and nitrogen to form ammonia is: N2 + 3H2 <=> 2NH3
