Question
For a reaction; $3 A \longrightarrow$ Products, it is found that the rate of reaction becomes nine times if concentration of $A$ is increased three times, calculate order of reaction.
Step 1
Step 1: The rate law for the reaction is given by $R = k[A]^n$, where $R$ is the rate of reaction, $k$ is the rate constant, $A$ is the concentration of reactant A, and $n$ is the order of reaction. Show more…

What is the reaction order if the reaction rate triples when the concentration of a reactant is increased by a factor of 3$?$
For a reaction $\mathrm{A}+\mathrm{B} \longrightarrow \mathrm{C}+\mathrm{D}$ if the concentration of A is doubled without altering the concentration of $\mathrm{B}$, the rate gets doubled. If the concentration of is increased by nine times without altering the concentration of $\mathrm{A}$, the rate gets tripled. The order of the reaction is: (a) 2 (b) 1 (c) $3 / 2$ (d) $4 / 3$
