The Essential part of Bohr’s Model is

Chemistry
1 answer:
IrinaVladis [17]3 years ago
4 0

Answer:The model states that electrons in atoms move in circular orbits around a central nucleus and can only orbit stably in certain fixed circular orbits at a discrete set of distances from the nucleus. These orbits are associated with definite energies and are also called energy shells or energy levels.

bohrs model and other models are really hard to understand but i hope this will help you!

Consider the following multistep reaction:
chubhunter [2.5K]

The question is incomplete, here is the complete question:

Consider the following multistep reaction:

C+D⇌CD (fast)

CD+D→CD₂ (slow)

CD₂+D→CD₃ (fast)

C+3D→CD₃

Based on this mechanism, determine the rate law for the overall reaction.

<u>Answer:</u> The rate law for the reaction is \text{Rate}=k'[C][D]^2

<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.

For the given chemical reaction:

C+3D\rightarrow CD_3

The intermediate reaction of the mechanism follows:

<u>Step 1:</u>  C+D\rightleftharpoons CD;\text{ (fast)}

<u>Step 2:</u>  CD+D\rightarrow CD_2;\text{(slow)}

<u>Step 3:</u>  CD_2+D\rightarrow CD_3;\text{(fast)}

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

Rate law for the reaction follows:

\text{Rate}=k[CD][D]           ......(1)

As, [CD] is not appearing as a reactant in the overall reaction. So, we apply steady state approximation in it.

Applying steady state approximation for CD from step 1, we get:

K=\frac{[CD]}{[C][D]}

[CD]=K[C][D]

Putting the value of [CD] in equation 1, we get:

\text{Rate}=k.K[C][D]^2\\\\\text{Rate}=k'[C][D]^2  

Hence, the rate law for the reaction is \text{Rate}=k'[C][D]^2

Please help with chemistry work
Andrei [34K]

Answer:

Explanation:

14:

a) Shared pairs = 6

per shared pair between each C-H bond.

and two shared pair between C=C thus total shared pairs are 6

a) Lone pairs = 0

b) Single bonds = 4

Double bonds = 1

Triple bonds = 0

c) Formula = C₂H₄

Name = Ethene

d) Lewis structure =  given structure is also Lewis structure.

13:

a) Shared pairs = 3

a) Lone pairs = 2

b) Single bonds = 0

Double bonds = 0

Triple bonds = 1

c) Formula = N₂

Name = Dinitrogen

d) Lewis structure = given structure is also Lewis structure.
