Unformatted text preview: of the forward reaction is great at the start of the reaction. As the reaction proceeds, the rate of the forward reaction decreases, due to a decrease in the concentration of the reactants. · On the other hand, the rate of the reverse reaction is very small at the start. As the reaction proceeds, the rate of the reverse reaction increases, due to an increase in the concentration of the products. · Eventually the rate of the forward react ion equals the rate of the reverse reaction. At this point, the reaction is said to have reached chemical equilibrium.
· At equilibrium, there are no further changes in the concentration of reactants or products. 4 Chemistry 52 Chapter 16 CHEMICAL EQUILIBRIUM 1) The same equilibrium mixture is obtained whether the reaction starts with reactants or products. However, this does not mean that the amount of reactant beco mes equal to the amount of product. 2) In some reversible react ions equilibrium is reached when most reactants have co mbined to form products. In these reactions, we say the equilibrium fav...
