3A → B + C
It would be a zero order reaction, when.
The rate of reaction is proportional to square of concentration of A.
The rate of reaction remains same at any concentration of A.
The rate remains unchanged at any concentration of B and C.
The rate of reaction doubles if concentration of B is increased to double.
In a first order reaction A → B, if k is rate constant and initial concentration of the reactant A is 0.5 M, then half-life is______________
For the reaction 2N2O5 → 4NO2 + O2, rate and rate constant are 1.02 × 10-4 and 3.4 × 10-5 s -1 respectively, then concentration of N2O5 at that time will be
