The correct answer is:
**a) they allow the equilibrium state to be determined based on the intensity of the color.**
Reactions involving colored reactants and products are useful for studying equilibrium because the intensity of the color can be measured, often using spectrophotometry, to determine the concentrations of the colored species at equilibrium. As the system reaches equilibrium, changes in color intensity correspond to the concentrations of reactants and products, allowing for quantitative analysis.
