What does it mean if KC 1 at equilibrium?

1 : The equilibrium constant Kc is a constant which represents how far the reaction will proceed at a given temperature. 2 : When Kc is greater than 1, products exceed reactants (at equilibrium). When much greater than 1, the reaction goes almost to completion. When Kc is less than 1, reactants exceed products.

What are the conditions for equilibrium chemistry?

chemical equilibrium, condition in the course of a reversible chemical reaction in which no net change in the amounts of reactants and products occurs. A reversible chemical reaction is one in which the products, as soon as they are formed, react to produce the original reactants.

What does it mean if the value of the equilibrium constant KEQ is less than 1 greater than 1 equal to 1?

If Keq is greater than 1, it means the concentrations of the products are greater than those of the reactants. If Keq is less than 1, it means the concentrations of the reactants are greater than the products. See also: chemical equilibrium, free energy.

What is physical equilibrium?

Physical equilibrium is defined as the equilibrium which develops between different phases or physical properties. In these processes, there is no change in chemical composition. It represents the existence of the same substance in two different physical states.

Can physical changes reach equilibrium?

An equilibrium can be established for a physical change—like this liquid to gas transition—as well as for a chemical reaction.

Why is equilibrium constant called constant?

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. …

How is equilibrium constant determined?

The numerical value of an equilibrium constant is obtained by letting a single reaction proceed to equilibrium and then measuring the concentrations of each substance involved in that reaction. The ratio of the product concentrations to reactant concentrations is calculated.
