(A) Let $R_1, R_2$,and $R_3$ be the rates of three reactions of first,second,and third-order,respectively,and $k$ be the rate constant for all three reactions.The rate laws are:$R_1 = k[A]^1$$R_2 = k[A]^2$$R_3 = k[A]^3$where $[A]$ is the concentration of reactant $A$ in moles per litre.Given that $[A] = 1$,we have:$R_1 = k(1)^1 = k$$R_2 = k(1)^2 = k$$R_3 = k(1)^3 = k$Therefore,$R_1 = R_2 = R_3$.
