What is the different between equilibrium constant and equilibrium

[plankk]

The equilibrium is the state in which the concentrations of the reactants and products have no net change over time. The equilibrium constant is the value which says us that products or reactants are more favourable.

[nanopico]

The equilibrium constant is describes the proportions of the products and reactants at equilibrium, and it is temperature dependent.

You might want to check out a physical chemistry text, eg "Physical Chemistry" by Atkins, or even the Wikipedia article on chemical equilibrium might get a handle on the concepts
