Respuesta :
The value of the equilibrium constant for the reaction is 12.0.
Reaction 1: A + B ⇌ C + D
Equilibrium Constant (K1): 4.0
Reaction 2: C + D ⇌ E + F
Equilibrium Constant (K2): 3.0
Equilibrium Constant for the overall reaction (A + B ⇌ E + F): K1 x K2 = 4.0 x 3.0 = 12.0
The equilibrium constant is a measure of the strength of an equilibrium reaction. It is a ratio of the concentrations of the products to the concentrations of the reactants at equilibrium. The value of the equilibrium constant can be used to determine the direction of the reaction and the magnitude of the shift in equilibrium. Additionally, the equilibrium constant can be used to calculate the equilibrium concentrations of the reactants and products.
example:
Nitrogen dioxide (NO2) and oxygen (O2) gas reacting to form nitrogen monoxide (NO) and oxygen (O2)
The reaction for this is 2NO2 + O2 → 2NO + O2 and the equilibrium constant for this reaction is Kc = [NO]2[O2]/[NO2]2. This reaction is an example of a redox reaction, where the oxidation state of nitrogen is reduced from +4 to +2 by the oxygen molecules. The equilibrium constant indicates the amount of product (NO) that will be formed at equilibrium. If the concentration of NO2 is increased, then more NO will be formed until the equilibrium is reached.
