Consider the following mechanism for the oxidation of bromide ions by hydrogen peroxide in aqueous acid solution. H+ + H2O2 ? H3O2+ (rapid equilibrium) H3O2+ + Br- ? HOBr + H2O (slow) HOBr+H+ +Br- ?Br2 +H2O(fast) Which rate law is consistent with this mechanism?

a. k[Br-][H+]-1[H2O2]-1
b. k[H+][H2O2][Br-]
c. k[H+][H2O2]
d. k[HOBr][H+][Br-]

The rate law for the reaction is

Explanation:

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:

Step 1:  

Step 2:  

Step 3:  

As, step 2 is the slow step. It is the rate determining step

Rate law for the reaction follows:

         ......(1)

As, 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:

Putting the value of in equation 1, we get:

Hence, the rate law for the reaction is

i don't see a text, but i am gonna assume this *orbit* the curved path, usually elliptical, described by a planet, satellite, spaceship, etc., around a celestial body, as the sun.

answer is: naturally occurring solid, inorganic compound or element is mineral.

minerals usually have crystalline form, that means than crystal constituents (atoms, molecules or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.

for example magnetite is a mineral of iron oxide (fe₂o₃).

calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (caco₃).

dolomite is an   carbonate mineral composed of calcium magnesium carbonate (camg(co₃)₂).
