Question

What is equilibrium constant expression?

(a) The ratio of the concentrations of the reactants and molar constant and products

(b) The ratio of the concentrations of the products and reactants

(c) The ratio of the concentrations of the reactants and products

(d) The ratio of the concentrations of the catalyst and products

I had been asked this question in homework.

Question is taken from Equilibrium Concentration Relationship in chapter Contact Equilibrium Separation Process of Food Processing Unit Operations

Answer 1

The correct option is (c) The ratio of the concentrations of the reactants and products

Explanation: The ratio of the concentrations of the reactants and products is called as equilibrium constant expression. When the reaction reaches equilibrium, the association between the concentrations of the reactants and products termed by the equilibrium constant expression is always same.
