Question

Which of the following can not be predicted from an equilibrium constant for a reaction?

• A. The extent of a reaction
• B. which direction a reaction will proceed by measuring the concentrations of reactants and products
• C. whether a system is at equilibrium by measuring the concentrations of the reactants and products.
• D. Nature of reactant and product.

Answer 1

The correct option is D Nature of reactant and product.

Equilibrium constant for a reaction predict:
the extent of a reaction;
which direction a reaction will proceed by measuring the concentrations of reactants and
products;
whether a system is at equilibrium by measuring the concentrations of the reactants and products.
But it can not predict the nature of reactant or product.
