Current Question (ID: 18270)

Question:

$\text{Which of the following statements about the order of reaction is incorrect?}$

Options:

1. $\text{Order is not influenced by the stoichiometric coefficient of the reactants.}$
2. $\text{Order of reaction is the sum of power to the concentration terms of reactants to express the rate of reaction.}$
3. $\text{The order of reaction is always a whole number.}$
4. $\text{Order can be determined by experiments only.}$

Solution:

$\text{If the rate of a reaction is given by } k[\text{A}]^x[\text{B}]^y \text{ then the order of the reaction is } x+y.$ $\text{This order can be a positive, negative number, zero, or even fractional.}$ $\text{It can be determined only experimentally and does not depend on the stoichiometric coefficients of reactants.}$ $\text{Hence, option 3rd is the answer.}$
