In the reaction, $A \to$ 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:

Answer:

Solution:

$r_{1} = k [A]^{n}$ and $r_{2} = k [2 A]^{n}$ $∵ r_{1} = r_{2} ∴ k [A]^{n} = k (2 [A])^{n}$ or, $2^{n} = 1$ or, $2^{n} = 2^{\circ} \Rightarrow n = 0$ It is a zero order reaction.
