Final answer:
At equilibrium, the equilibrium constant (K) shows how the concentrations of the products vary with the concentration of the reactants. The magnitude of K determines the composition of the equilibrium mixture. However, the standard electrode potential (Eᶜᵉˡˡ) is not directly related to the equilibrium constant or reaction quotient.
Step-by-step explanation:
At equilibrium, the equilibrium constant (K) is a mathematical relationship that shows how the concentrations of the products vary with the concentration of the reactants. It is a unitless quantity and indicates the ratio of the rate constants for the forward and reverse reactions at equilibrium.
When Kƒ is much greater than Kr, the equilibrium constant will be a large number, and the concentration of products at equilibrium will predominate, indicating an essentially irreversible reaction. Conversely, when Kƒ is much smaller than Kr, the equilibrium constant will be a very small number, and the reaction will produce almost no products as written.
The standard electrode potential (Eᶜᵉˡˡ) is a measure of how easily a species is reduced or oxidized in a redox reaction. It provides information about the tendency of the reaction to occur. However, it is not directly related to the equilibrium constant or the reaction quotient.
