Why are equilibrium constants useful?

A. One number that gives us information about the relative concentrations of reactant and product.

B. One number that gives us information about the relative production rates of reactant and product.

C. One number that gives us information about the relative activation energies of reactant and product.

D. None of the above.

What will be the answer to this problem?

I believe the answer would be A, because the equilibrium constant gives a ratio which includes products and reactants at equilibrium. For example, when K is greater than one the reaction has mostly products and when K is less than one the reaction has mostly reactants.

The answer is A for this question because the equilibrium constant is giving a ratio of the concentrations of products and reactants at equilibrium, which gives the relative concentrations of products and reactants at equilibrium.

Also B is incorrect because the equilibrium constant gives us the RATIO of concentrations of products vs. reactants- we cannot calculate their exact rates. C is incorrect because it's irrelevant at the moment- activation energies relate more to the thermodynamic unit.
