Does the value of equilibrium constant depend on the initial concentration of the reactants and products?

The value of the equilibrium constant for any reaction is only determined by experiment. As detailed in the above section, the position of equilibrium for a given reaction does not depend on the starting concentrations and so the value of the equilibrium constant is truly constant.

Why is the equilibrium constant important?

The equilibrium constant is important because it gives us an idea of where the equilibrium lies. The larger the equilibrium constant, the further the equilibrium lies toward the products.

Does the value of the equilibrium constant change when the concentration of either the reactants or products is altered?

Changes in concentration do not affect the value of Kc .

Why is equilibrium constant important?

Why is it important to find the equilibrium constant?

All equilibria have different ratios of products to reactants. As an example, let’s consider a reaction in which the forward reaction takes place quickly and the reverse reaction is slow.

What is the equilibrium constant of a reaction?

As except T all other terms would be constant for the given operating conditon.s So k ( rate constant )depends on temperature (not on concentration) and hence the equilibrium constant as it is the ratio of two rate constants. For a reversible reaction, if the concentration of the reactant is doubled, what will the equilibrium constant be?

What is the intermediate value of equilibrium constant 10 3?

Case 2: Intermediate value of equilibrium constant (10 -3 to 10 3) show that the concentration of the reactants and products are comparable. H 2 (g) + I 2 (g) ⇌ 2HI (g) ⇒ Kc = 57 at 700 K.

What is the unit of K in equilibrium constant?

NOTE: K is unitless and we use [A] to represent the concentration of “A”, but this is really a simplification, and equilibrium constants are calculated using “effective concentrations,” or activities, of reactants and products, which are the ratios of the measured concentrations to a standard state of 1 M.

What are the effects of changes in concentration on equilibrium?

If a system at equilibrium is subjected to some change in concentration, pressure, temperature, etc., the equilibrium is altered and the reaction takes place in some direction until the system returns to equilibrium once again Change in concentration, pressure, catalyst, inert gas addition, etc. have NO effect on Equilibrium CONSTANT.
