Effect of Concentration Changes on Equilibrium

Very Easy General Chemistry Chemical Equilibrium

In a chemical equilibrium, the rate at which the reactants are converted to products is equal to the rate at which the products are converted back to reactants. Consider the following reversible reaction:

A + B <=> C + D

If the concentrations of A and B are increased, what will be the immediate effect on the equilibrium position of the reaction?

The equilibrium will shift to the left, producing more A and B.

The equilibrium will shift to the right, producing more C and D.

The equilibrium will not change at all.

The reaction will stop completely.
