The rate constant is unmerically the same for three reactions of first, second and third order respectively, the unit of concentration being in moles per litre. If `R_(1), R_(2) and R_(3)` are the rates of three reactions of first, second and third order respectively aqnd K is the rate constant, which of the following relationships is valid for the three reactions.A. `R_(1)= R_(2) = R_(3)`B. `R_(1)ltT_(2)ltR_(3)`C. `R_(3)ltR_(2)ltR_(1)`D. All of these |

Answer» Correct Answer - D Considring the rate law expressions (for a reation `ArarrB)` we have `R_(1)=k[A]` `R_(2)=k[A]^(2)` `R_(3)=k[A]^(3)` `K` is the rate constant, which is the same for the three reactions and `[A]` is the concentration of the reaction `A` in moles per litre. `[A]=1,R_(1)=R_(2)=R_(3)` `[A]= gt1,R_(3)gtR_(2)gtR_(1)` `[A]= lt 1,R_(1)=R_(2)gtR_(3)` |
