The reaction $2 \mathrm{~A} \rightarrow \mathrm{B}+\mathrm{C}$, would be a zero-order reaction when:

The reaction $2 \mathrm{~A} \rightarrow \mathrm{B}+\mathrm{C}$, would be a zero-order reaction when:
  1. the rate of the reaction is proportional to the square of concentration of 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

The characteristic of zero-order reaction is Rate of reaction depends only on concentration of reactants. A reaction is zero-order if concentration data is plotted versus time and the result is a straight line.
