Kc at 457 K is 4.88 × 10⁵.
The ratio of the equilibrium concentrations of the products over the equilibrium concentrations of the reactants, each raised to the power of their respective stoichiometric coefficients, is known as the equilibrium constant, or Kc.
The reaction's forward motion at a specific temperature is represented by the equilibrium constant Kc. 8.2. 2: When Kc exceeds 1, products outweigh reactants (at equilibrium). When much more than 1, the reaction virtually comes to an end. When Kc is below 1, more reactants than products are produced.
The amount that a reaction will advance is determined by the equilibrium constant, K: The equilibrium concentration of the products is high if K is a large number.
