In the reaction, A→\mathrm{A} \rightarrow products, If the concentration of the reactant is doubled rate of the reaction remains unchanged. The order of the reaction with respect to A is

Options

  1. A11
  2. B22
  3. C0.50.5
  4. D00

Correct answer

D. 00

Step-by-step solution

r1=k[A]nr_1=k[A]^n and r2=k[2A]n∵r1=r2∴k[A]n=k(2[A])nr_2=k[2 A]^n\because \quad \mathrm{r}_1=\mathrm{r}_2 \quad \therefore \mathrm{k}[\mathrm{A}]^{\mathrm{n}}=\mathrm{k}(2[\mathrm{ A}])^{\mathrm{n}} or, 2n=1\quad 2^n=1 or, 2n=2∘⇒n=02^{\mathrm{n}}=2^{{}^{\circ}} \Rightarrow \mathrm{n}=0 It is a zero order reaction.
