Vedclass · Answer

(A) The rate of a chemical reaction is directly proportional to the concentration of the reactants according to the rate law,$Rate = k[A]^x[B]^y$. As the reaction proceeds,the concentration of reactants decreases over time,which leads to a decrease in the rate of reaction. For zero-order reactions,the rate remains constant,while for first or higher-order reactions,it decreases. Therefore,the statement that the rate decreases or remains constant with the passage of time is correct.
