Step 1
The effect of changes in the concentration of chemical substances in equilibrium
Answer
Le Chatelier's principle states that if an equilibrium system is subjected to a change in concentration, temperature, or pressure, the system will adjust itself to counteract that change and restore a new equilibrium. Therefore, the prediction that can be made using Le Chatelier's principle is:
(D) The effect of changes in the concentration of chemical substances in equilibrium.
This means that if the concentration of a reactant or product is changed, the position of equilibrium will shift to either the right or left, thus favoring the formation of products or reactants to minimize the effect of the concentration change.
