There is an error in the rate-determining step of the following proposed mechanism.

Chemistry
1 answer:
yulyashka [42]3 years ago
5 0

Answer:

The steps with correct mechanism are given below:

C

1) CH₄(g) + Cl(g) → CH₃(g) + HCl(g) : This is a slow step.

The rate is given as: R1 = k₁[CH₄][Cl]  

2) CH₃(g) + Cl₂(g) → CH₃Cl(g) + Cl(g): This is a fast step.

The rate is given as: Rate = k₂[CH₃][Cl₂]  

∴ CH₄(g) + Cl₂(g) → CH₃Cl(g) + HCl(g)

Here, the slowest step will be the rate-determining step.

What is the effect of thermal energy on the atoms/molecules in a sample of matter?​
Anestetic [448]

Answer:

When heat is added to a substance, the molecules and atoms vibrate faster. As atoms vibrate faster, the space between atoms increases. The motion and spacing of the particles determines the state of matter of the substance. The end result of increased molecular motion is that the object expands and takes up more space.

Damm [24]
<h3>Answer:</h3>

b. 1 Potassium  atom

c. 1 bromine atom

<h3>Explanation:</h3>

What is a compound?

  • A compound is a substance that is made up of atoms from different elements.
  • The formula of a compound shows the elements making up the compound.
  • Additionally, the formula of compound shows the number atoms of each element making up the compound.

In this case;

We are given the Formula KBr

  • This is the formula of the compound potassium bromide.
  • From the formula, we can tell that the compound is made up of potassium and bromine atoms.
  • The formula also shows the number of atoms of each element, that is, 1 potassium atom and 1 bromide atom.

<span>Yes, mass is conserved. When sodium hydroxide (clear solution) and copper sulfate (blue solution) are mixed, they form a copper hydroxide (a blue solid) and sodium sulfate (a clear solution). This can be tested simply. First weigh the masses (10 g and 57 g, which totals 67 g)) of the two starting solutions prior to mixing. Then mix and allow the reaction to occur and weigh the mass of the mixture (10g + 57 g = 67 g). The two solutions should have the same mass and therefore demonstrate conservation of mass.</span>

A sample of gas occupies 1.2 L at 12.0oC. Assuming pressure remains the same, what would be the volume (in L) of this gas at 67o
liraira [26]
V1/T1 = V2/T2
V1 = 1.2 L
T1 = 12.0 + 273 = 285 K
T2 = 67.0 +273 = 340 K

1.2/285 = V2 / 340
V2 = 1.4 L
