Answer:
Ley.
Explanation:
En la teoría de la ciencia, la regularidad de los procesos en la naturaleza se denomina ley de la naturaleza. Las leyes naturales se diferencian de otras leyes en que los seres humanos no pueden ponerlas en vigor ni anularlas a su discreción. En tal sentido, la composición química del agua es indudablemente una ley natural, en tanto el hombre no puede modificarla sin modificar las características inherentes del agua como tal.
<u>Answer:</u> The rate law for the reaction is ![\text{Rate}=k'[H+][H_2O_2][Br^-]](https://tex.z-dn.net/?f=%5Ctext%7BRate%7D%3Dk%27%5BH%2B%5D%5BH_2O_2%5D%5BBr%5E-%5D)
<u>Explanation:</u>
Rate law is the expression which is used to express the rate of the reaction in terms of the molar concentration of reactants where each term is raised to the power their stoichiometric coefficient respectively from a balanced chemical equation.
In a mechanism of the reaction, the slow step in the mechanism determines the rate of the reaction.
The chemical equation for the oxidation of bromide ions by hydrogen peroxide in aqueous acid solution follows:
The intermediate reaction of the mechanism follows:
<u>Step 1:</u> 
<u>Step 2:</u> 
<u>Step 3:</u> 
As, step 2 is the slow step. It is the rate determining step
Rate law for the reaction follows:
![\text{Rate}=k[H_3O_2^+][Br^-]](https://tex.z-dn.net/?f=%5Ctext%7BRate%7D%3Dk%5BH_3O_2%5E%2B%5D%5BBr%5E-%5D)
......(1)
As, ![[H_3O_2^+]](https://tex.z-dn.net/?f=%5BH_3O_2%5E%2B%5D)
is not appearing as a reactant in the overall reaction. So, we apply steady state approximation in it.
Applying steady state approximation for from step 1, we get:
![K=\frac{[H_3O_2^+]}{[H^+][H_2O_2]}](https://tex.z-dn.net/?f=K%3D%5Cfrac%7B%5BH_3O_2%5E%2B%5D%7D%7B%5BH%5E%2B%5D%5BH_2O_2%5D%7D)
![[H_3O_2^+]=K[H^+][H_2O_2]](https://tex.z-dn.net/?f=%5BH_3O_2%5E%2B%5D%3DK%5BH%5E%2B%5D%5BH_2O_2%5D)
Putting the value of in equation 1, we get:
![\text{Rate}=k.K[H^+][H_2O_2][Br^-]\\\\\text{Rate}=k'[H+][H_2O_2][Br^-]](https://tex.z-dn.net/?f=%5Ctext%7BRate%7D%3Dk.K%5BH%5E%2B%5D%5BH_2O_2%5D%5BBr%5E-%5D%5C%5C%5C%5C%5Ctext%7BRate%7D%3Dk%27%5BH%2B%5D%5BH_2O_2%5D%5BBr%5E-%5D)
Hence, the rate law for the reaction is
Wurtz reaction is a special type of organic reaction involving the synthesis of aliphatic hydrocarbons from two molecules of an alkyl halide and two atoms of sodium in the presence of dry ether solution
Please bear in mind that wurtz reaction fails whenever tertiary alkyl halides are used.
An example of Wurtz reaction is given below:
2R – X + 2Na → R–R + 2Na + X−
<h3>What are organic compounds?</h3>
Organic compounds can simply be defined as those classes of organic molecules which contain carbon atoms covalently bonded to hydrogen atoms (C-H bonds).
Below are some few general characteristics of organic compounds:
- All organic compounds contain carbon.
- Most of them are flammable.
- They are all soluble in non-polar solvents
- Most organic compounds / substances are covalently bonded molecules
Some classes of organic compounds are:
So therefore, Wurtz reaction is a special type of organic reaction involving the synthesis of aliphatic hydrocarbons from two molecules of an alkyl halide and two atoms of sodium in the presence of dry ether solution
