For conversion of compound A→BA \to B, the rate constant of the reaction was found to be 4.6×10−5Lmol−1s−14 . 6 \times {10}^{- 5}Lmol - 1 {s}^{- 1}. The order of the reaction is _____ .

Correct answer

0

Step-by-step solution

Rate(r) =k[A]n= k{\left[A\right]}^{n}

⇒k=rate[A]n⇒ k = \dfrac{rate}{{\left[A\right]}^{n}}

Unit of rate constant is related to order of reaction(n)( n ) by the relation: (conc.)1−ntime−1{\left(conc .\right)}^{1 - n}{time}^{- 1}

Thus,
⇒(Lmol−1)⇒1−n=−1n=2\begin{array}{ll}⇒ \left({Lmol}^{- 1}\right) ⇒ 1 - n = - 1 \\ n = 2\end{array}
