Chemical Kinetics - Result Question 41
####41. $3 A \to B+C$, it would be a zero order reaction when
[2002]
(a) the rate of reaction is proportional to square of concentration of $A$
(b) the rate of reaction remains 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
Show Answer
Solution:
- (b) For reaction $3 A \longrightarrow B+C$
If it is zero order reaction $r=k[A]^{0}$, i.e the rate remains same at any concentration of ‘A’.
For zero order reaction rate of reaction is independent of reactant concentration.
