Whether Reaction 1 at equilibrium or Reaction 2 not at equilibrium does any work or not. Introduction: The equilibrium constant represents the relation between reactants and products in a reaction at equilibrium. The concentrations of reactants and products are constant at equilibrium. Under conditions of a biochemical reaction, free energy (G) is defined as the amount of energy available to perform work.
