Question

2A $\rightarrow$ B + C
It would be a zero-order reaction when

• A. The rate of reaction is proportional to square of conc. of A
• B. The rate of reaction remains same at any conc. of A
• C. The rate remains unchanged at any conc. of B and C
• D. The rate of reaction doubles if conc. of B is increased to double

Answer 1

Answer: (B)

The rate of reaction remains same at any conc. of A

Answer 2

Reactions in which rate is independent of concentration of reactant is zero order reaction.

So, the correct option is (B): The rate of reaction remains same at any conc. of A.
