Equilibrium constant
Equilibrium constant is a mathematical quantity which expresses the relationship between products and reactants of a reaction at equilibrium with respect to a specific unit. In other words, equilibrium constant is the reaction quotient of a chemical reaction at chemical equilibrium. The equilibrium constant can help us to understand whether the reaction tends to have a higher concentration of products or reactants at equilibrium. We can also use to Equilibrium constant determine if the reaction is already at equilibrium.
