Propose a rate law consistent with the mechanism.
Please show and explain everything.
Answers
Based on the mechanism shown above, the correct rate law that is consistent with the sample reaction is [tex]B+D \rightarrow ^{k_{-1}} E+C[/tex].
What is the rate law?Rate law can be defined as a chemical equation that is used to relate the initial (forward) chemical reaction rate with respect to the concentrations of both the chemical reactants and constant parameters.
Mathematically, the rate law is given by this formula:
[tex]R = K[A]^x[B]^y[C]^z[/tex]
Where:
k is the rate constant.A is the concentration of reactant A.B is the concentration of reactant B.C is the concentration of reactant C.x, y, and z are the order of the reaction.Based on the mechanism shown above, the correct rate law that is consistent with the sample reaction is as follows:
[tex]B+D \rightarrow ^{k_{-1}} E+C[/tex]

Scientists have observed that the average surface temperature of the Earth has been increasing. This increase has
affected the oceans. Glaciers and ice sheets melt, and water from this melting process becomes part of the oceans.
The increasing temperature of the Earth's surface also warms ocean waters. As a result, the volume of the oceans
expands. These two events affect sea level.
What would happen to sea level if the average surface temperature trend that was observed since the 1960s
continues?
A) Sea level will rise, then will suddenly fall.

Ozone, O3, an unstable, blue, diamagnetic gas with a characteristic pungent odor, protects the earth and its inhabitants from intense ultraviolet radiation from the sun.[tex]\rightarrow[/tex]Ozone is an allotropic molecular form of oxygen containing three atoms of oxygen (O3). Ozone O3 is generated through the passage of oxygen O2 through a high voltage potential resulting in the attachment and formation of a third oxygen atom.

Answers
For an impure sample of potassium hydrogen phthalate, the percentage of potassium hydrogen phthalate is
m'=39.3%
What is the percentage of potassium hydrogen phthalate if 2.81 g of the mixture required 35.61 mL of 0.152 mol/L NaOH to reach the end point?Generally, the equation for the mol base is mathematically given as
mol base = M*V
mol base = 0.152*35.61
mol base = 5.41272 mmol
In conclusion
mass = mmol/1000*MW
m== 5.41272 /1000*204.22
m= 1.1053 g of KHP
Hence, m'=39.3%

The reaction which is a self-sustaining series of chemical reactions in which the products of one reaction are the reactants in the next reaction is chain reactions.
What are reactants and products?Reactants are those species which are present at the initial state of the reaction and at the end of the reaction we obtain products.
If in any chemical reactions, reactants are combined for the formation of products and for the further process obtained product will act as reactant and that chemical reactions are known as chain reactions. Because this process continues for long time.
