Chemical equilibrium is a dynamic process where the rates of forward and reverse reactions are equal. At equilibrium, the concentrations of reactants and products are stable, and the reaction quotient (Q) equals the equilibrium constant (K). The equilibrium constant is a value that describes the ratio of the concentrations of products to reactants at equilibrium.
This reaction is an example of a complex formation reaction, where the iron(III) ion reacts with the thiocyanate ion to form a blood-red colored complex. Stpm Chemistry Experiment 10 201314
The calculated value of K is:
