Chemical Kinetics Ques 20
20. Which one of the following statements for the order of a reaction is incorrect?
[2011]
(a) Order can be determined only experimentally.
(b) Order is not influenced by stoichiometric coefficient of the reactants.
(c) Order of reaction is sum of power to the concentration terms of reactants to express the rate of reaction.
(d) Order of reaction is always whole number.
Show Answer
Solution:
- (d) order of reaction can be zero, whole number or fractional.
The order w.r.t a reactant can be negative also as in this case:
$ \begin{aligned} & 2 O_3 \rightarrow 3 O_2 \\ & \text{ Rate- } k[O_3]^{2}[O_2]^{-1} \end{aligned} $
