Which of the following is not true for the order of a reaction?a)Order...
Introduction:
The order of a reaction refers to the exponent to which the concentration of a reactant is raised in the rate equation. It represents the influence of the concentration of a reactant on the rate of reaction. This order can be determined experimentally by studying the changes in the rate of reaction with respect to the changes in concentration of the reactants.

Explanation:
Let's analyze each statement to determine which one is not true for the order of a reaction.

a) Order of reaction is always a whole number:
This statement is not true. The order of a reaction can be any real number, including fractional or negative values. The order of a reaction is determined experimentally and does not need to be a whole number. It represents the relationship between the concentration of a reactant and the rate of reaction.

b) Order can only be determined experimentally:
This statement is true. The order of a reaction cannot be predicted based solely on the stoichiometric coefficients of the reactants. It can only be determined through experimental observations, such as measuring the initial rates of reaction with different reactant concentrations.

c) Order is not influenced by stoichiometric coefficient of the reactants:
This statement is not true. The order of a reaction is influenced by the stoichiometric coefficients of the reactants. The rate equation is derived from the balanced chemical equation, which includes the stoichiometric coefficients. The powers to which the concentration terms are raised in the rate equation correspond to the stoichiometric coefficients of the reactants.

d) Order of reaction is the sum of the powers of concentration terms of reactants to express the rate of reaction:
This statement is true. The order of a reaction is determined by summing the powers of the concentration terms of the reactants in the rate equation. For example, if the rate equation is given by rate = k[A]^m[B]^n, the order of the reaction would be m + n.

Conclusion:
Based on the analysis, the statement that is not true for the order of a reaction is option 'A' - "Order of reaction is always a whole number". The order of a reaction can be any real number and is not limited to whole numbers.

Which of the following is not true for the order of a reaction?a)Order...
Correct option is A)
If rate is given by: rate =k[A]x[B]y
then the order =x+y.
This order can be a positive, negative no., zero or even fractional. It can be determined only experimentally and does not depend on stoichiometric coefficients of reactants.
