How a reaction can be at equilibrium but not have the same concentration of reactants and products?

Chemical equilibrium is a dynamic process. The forward and reverse reactions continue to occur even after equilibrium has been reached. However, because the rates of the reactions are the same, there is no change in the relative concentrations of reactants and products for a reaction that is at equilibrium.

Are the concentrations of the reactants and products equal at equilibrium?

All reactions tend towards a state of chemical equilibrium, the point at which both the forward process and the reverse process are taking place at the same rate. Since the forward and reverse rates are equal, the concentrations of the reactants and products are constant at equilibrium.

Why does equilibrium constant not change with concentration?

The equilibrium constant does not change because it is a measure of the relative concentrations of the reactants and products at equilibrium.

What happens to the concentration of reactants as a reaction proceeds?

When the concentrations of the reactants are raised, the reaction proceeds more quickly. This is due to an increase in the number of molecules that have the minimum required energy. For gases, increasing pressure has the same effect as increasing concentration.

What happens to the concentrations of the reactants and products during the course of a chemical reaction?

What happens to the concentrations of the reactants and products during the course of a chemical reaction? Concentration of reactants decreases and the concentration of products increases. The activated complex is a transition state between reactants and products.

How do the concentrations of reactants and products change over time?

The concentrations of the reactants and products do not change with time. This does not mean that the concentrations of the reactants and products are equal but that their concentrations are unchanging because the forward and reverse reactions are occurring at equal rates.

What happens when you decrease the concentration of reactants?

When the concentration of all the reactants increases, more molecules or ions interact to form new compounds, and the rate of reaction increases. When the concentration of a reactant decreases, there are fewer of that molecule or ion present, and the rate of reaction decreases.
