Which of the following statement is true for order of a reaction?a)It ...
**Explanation:**
The order of a reaction is a measure of how the concentration of reactants affects the rate of the reaction. It is determined experimentally by studying the rate of reaction under different conditions, such as varying the concentration of reactants.
The statement that is true for the order of a reaction is:
**a) It can have a fractional value.**
This means that the order of a reaction is not limited to whole numbers; it can also be a fraction or a decimal. The order of a reaction is determined by the rate equation derived from experimental data, which relates the rate of the reaction to the concentrations of the reactants.
**Reasoning:**
The order of a reaction is not necessarily related to the stoichiometric coefficients of the reactants and products. The stoichiometric coefficients only indicate the ratio in which the reactants combine to form products, but they do not determine the order of the reaction.
The order of a reaction cannot be determined solely from the balanced chemical equation. The balanced equation only provides information about the stoichiometry of the reaction, not the rate at which it occurs.
The order of a reaction can only be determined experimentally by studying the rate of the reaction under different conditions. By varying the concentrations of the reactants and measuring the corresponding rates, the order of the reaction can be determined.
**Example:**
Let's consider a hypothetical reaction:
A + B -> C
If the rate equation for this reaction is determined to be:
Rate = k[A]^0.5[B]^2
Then the order of the reaction with respect to A is 0.5 and with respect to B is 2. These values are not whole numbers but fractional and integer values, respectively. Hence, the order of a reaction can have a fractional value, which supports the statement a) as the correct answer.
