Which of the following statements concerning equilibrium constants is true? The equilibrium constant of the reverse reaction is equal in magnitude but opposite in sign of the forward reaction. When related reactions are added together, their equilibrium constants are added together. When the coefficients in a balanced chemical reaction are multiplied by two, the equilibrium constant is multiplied by two. When the coefficients in a balanced chemical reaction are multiplied by two, the equilibrium constant is not affected. When the coefficients in a balanced chemical reaction are multiplied by two, the equilibrium constant is squared.

The equilibrium constant of a chemical reaction is the value of its reaction quotient at chemical equilibrium, a state approached by a dynamic chemical system after sufficient time has elapsed at which its composition has no measurable tendency towards further change.

The equilibrium depends on the following:-

When the coefficients in a balanced chemical reaction are multiplied by two, the equilibrium constant is not affected.  The equilibrium constant of a reaction is known to remain steady.

Even if all the coefficients of all the species in the reaction are multiplied by two, the value of the equilibrium constant will remain the same because the equilibrium position will not change as a result of that.

Explanation:

The equilibrium constant of a reaction is known to remain steady.

Even if all the coefficients of all the species in the reaction are multiplied by two, the value of the equilibrium constant will reamin the same because the equilibrium position will not change as a result of that.
