$3 \mathrm{~A} ightarrow \mathrm{B}+\mathrm{C}$, it would be a zero order reaction when

$3 \mathrm{~A} ightarrow \mathrm{B}+\mathrm{C}$, it would be a zero order reaction when
  1. the rate of reaction is proportional to square of concentration of $\mathrm{A}$
  2. the rate of reaction remains same at any concentration of A
  3. the rate remains unchanged at any concentration of $\mathrm{B}$ and $\mathrm{C}$
  4. the rate of reaction doubles if concentration of $\mathrm{B}$ is increased to double

Solution

For reaction $3 \mathrm{~A} \longrightarrow \mathrm{B}+\mathrm{C}$
If it is zero order reaction $\mathrm{r}=\mathrm{k}[\mathrm{A}]^{0}$, i. e the rate remains same at any concentration of ' $\mathrm{A}^{\prime}$. i.e independent upon concentration of A. ~
