Figure 18.2, page 542: compare the rates A “rate” is a measure of the speed of any change that occurs within an interval of time In chemistry, reaction rate is expressed as the amount of reactant changing per unit time. Example: 3 moles/year, or 5 grams/second

rium has been reached between the two chemical reactions. Both reac-tions continue, but there is no net change in the composition of the system. A reversible chemical reaction is inchemical equilibriumwhen the rate of its forward reaction equals the rate of its reverse reaction and the concentrations of its products and reactants remain ...
