NEET 2002 Chemistry question

It would be a zero order reaction when :

(1)The rate of reaction is proportional to square of conc. of A
(2)The rate of reaction remains same at any conc. of ACorrect
(3)The rate remains unchanged at any conc. of B and C
(4)The rate of reaction doubles if conc. of B is increased to double

Answer: (2)

Solution

For a zero-order reaction , i.e. the rate is independent of the concentration of the reactant A and remains constant at any concentration of A: option (2). Option (1) describes a second-order reaction. Options
