Question

$3A⟶B+C$

It would be a zero-order reaction when:

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

Answer 1

Answer: (B)

The rate of reaction remains the same at any concentration of $A$

For reaction, $3A⟶B+C$

If it is zero order reaction, therefore the rate remains same at any concentration of '$A$' or $\frac{dx}{dt}=k[A{]}^0$.

It means that the rate is independent of the concentration of reactants.

Hence, option B is correct.
