Emerson Molina · Answer 1

Time remaining to reach equilibrium

Explanation:

Direction of a reaction

The equilibrium constant is related to this variable. If we have a higher constant value the reaction would be displaced to the products and if we have a smaller constant value the reaction would be displaced to the reactives.

Extent of a reaction

We can know with the constant value if a reaction is optimal to synthesize the desired product. Also, it gives an idea of how many products we will have in a specific reaction. In addition, we can modify the variables of the reaction to optimize the amount of products given by the reaction. So, in conclusion, Keq is related to this variable.

Quantity of a reactants remaining at equilibrium

The mathematical form of Keq we have to use the concentrations of the products and the reactives, also, as we say before we can know with the Keq if the reaction is displaced to right or left (products or reactives). Therefore if we have, for example, a high Keq value we know that the reaction is displaced to the right, so the amount of reactants at the end must be small.

Time remaining to reach equilibrium

Keq is no related with time. With this value, we can predict the direction of the equilibrium but we can not know how much time is going to take to reach the equilibrium.
