(N/A) The rate of a reaction depends on the concentration of reactants. As the reaction progresses,the concentration of reactants decreases because the reactants are converted into products. According to the rate law,the rate is directly proportional to the concentration of reactants. Therefore,as the concentration of reactants decreases,the rate of the reaction also decreases.
