If the rate constant is numerically the same for first-, second-, and third-order reactions, respectively, and all reactions are of the form A→products\text{A}\rightarrow\text{products}, which of the following is correct? (a) If [A]=1[\text{A}]=1, then r1=r2=r3r_1=r_2=r_3. (b) If [A]<1[\text{A}]<1, then r1>r2>r3r_1>r_2>r_3. (c) If [A]>1[\text{A}]>1, then r3>r2>r1r_3>r_2>r_1. (d) All
