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.
The rate constants k1 and k2 for two different reaction are 1016.e-2000/T and 1015.e-1000/T, respectively. The temperature at which k1 = k2 is
