`2A rarr B + C`. It would be a zero-order reaction whenA. the rate of reaction is proportional to square of concentration of AB. the rate of reaction remains same at any concentration of AC. the rate remains unchanged at any concentration of B and CD. the rate of reaction doubles if concentration of B is incereased to double

Answer» Correct Answer - B
For the reaction
`3ArarrB+c`
the differential rate law is
Rate `=k[A]^(x)`
where `x` the order of reaction. Zero order reaction means that the rate of the reaction is proportional to zero power of the concentration of reactant i.e., `x=0` . Thus,
Rate `=k`
Hence, the rate of reaction remains the same at any concentration of `A` .
