Q. Which one of the following statements for the order of a reaction is incorrect?
A) Order of reaction is always whole number
B) Order can be determined only experimentally
C) Order is not influenced by stoichiometric coefficient of the reactants
D) Order of reaction is sum of power to the concentration terms of reactants to express the rate of reaction
Explanation
[Solution from source] Order is an experimental quantity and can be zero, fractional or even negative, so the claim that it is always a whole number is incorrect. It is determined experimentally, does not have to follow stoichiometric coefficients, and equals the sum of the powers of concentration terms in the rate law. Answer (1).
