Relationship between kc and Qc to predict the direction of the reaction

Answer 1

The relationship between the equilibrium constant (Kc) and the reaction quotient (Qc) can be used to predict the direction in which a reaction will proceed.

If Qc < Kc, then the reaction will proceed in the forward direction, meaning that the reactants will continue to be converted into products until Qc reaches Kc.

If Qc = Kc, then the reaction is at equilibrium, with the concentrations of reactants and products remaining constant.

If Qc > Kc, then the reaction will proceed in the reverse direction, meaning that the products will be converted back into reactants until Qc reaches Kc.

In summary, if Qc is less than Kc, the reaction will proceed forward; if Qc is equal to Kc, the reaction is at equilibrium; and if Qc is greater than Kc, the reaction will proceed in the reverse direction.
