Question

what is the order of the reaction whose unit of rate constant and rate of reaction are same ?

Answer 1

$$\begin{gathered} Considerthereaction \\ A+B\to Product \\ Rateofthereaction=K\left[A{]}^x\right[B{]}^y \\ ThegivenconditionisbothRandKarehavingsameunit.Thatmeans \\ \left[A{]}^x\right[B{]}^y=\left[A{]}^0\right[B{]}^0(x=0andy=0) \\ R=K\left[A{]}^0\right[B{]}^0=K \\ Thustheorderofthereaction=x+y=0 \\ SoforazeroorderreactionR=Kandbothhavesameunit. \end{gathered}$$
