Question

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

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

Answer 1

The correct option is A 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.
