<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
The circulatory system works with the digestive system. Once the food is digested, the circulatory systems absorb and uses the nutrients in the food. If the digestive system were to break down, the circulatory will not have the nutrients it needs to sufficiently run the body.

Answer: To test the properties of the particles, Thomson placed two oppositely-charged electric plates around the cathode ray. The cathode ray was deflected away from the negatively-charged electric plate and towards the positively-charged plate. This indicated that the cathode ray was composed of negatively-charged particles.
Thomson also placed two magnets on either side of the tube, and observed that this magnetic field also deflected the cathode ray. The results of these experiments helped Thomson determine the mass-to-charge ratio of the cathode ray particles, which led to a fascinating discovery−-−minusthe mass of each particle was much, much smaller than that of any known atom. Thomson repeated his experiments using different metals as electrode materials, and found that the properties of the cathode ray remained constant no matter what cathode material they originated from. From this evidence, Thomson made the following conclusions:
The cathode ray is composed of negatively-charged particles.
The particles must exist as part of the atom, since the mass of each particle is only ~1/2000 the mass of a hydrogen atom.
These subatomic particles can be found within atoms of all elements.
While controversial at first, Thomson's discoveries were gradually accepted by scientists. Eventually, his cathode ray particles were given a more familiar name: electrons. The discovery of the electron disproved the part of Dalton's atomic theory that assumed atoms were indivisible. In order to account for the existence of the electrons, an entirely new atomic model was needed.
