Which of the following are correct for zero-order reactions?

Chemistry
1 answer:
GREYUIT [131]3 years ago
5 0

Answer:

The answer is "Choice A and Choice B"

Explanation:

The Zero-Order reactions are usually found if a substrate, like a surface or even a catalyst, is penetrated also by reactants. Its success rate doesn't depend mostly on the amounts of the various reaction in this reaction.

Let the Rate = k

As \frac{dx}{dt} \ rate\ \  K_0 doesn't depend on reaction rate, a higher reaction rate does not intensify the reaction.

By the rate k_0 =\frac{dx}{dt}, the created based and the reaction rate is about the same.

Iron (III) oxide is formed when Iron combines with oxygen in the air. How many grams of Fe₂O₃ are formed when 16.7 grams of reac
sladkih [1.3K]

Answer:

23.9g of Fe₂O₃ are produced

Explanation:

<em>Are formed when 16.7g of Fe reacts completely...</em>

<em />

Based on the reaction:

4Fe + O₃ → 2Fe₂O₃

<em>4 moles of Iron react per 1 mole of O₃ producing 2 moles of Fe₂O₃.</em>

<em />

To solve this question we need to convert the mass of iron to moles. The ratio of reaction is 2:1 -That is, 2 moles of Fe produce 1 mole of Fe₂O₃-. Thus, we can find the moles of Fe₂O₃ produced and its mass:

<em>Moles Fe -Molar mass: 55.845g/mol-:</em>

16.7g Fe * (1mol / 55.845g) = 0.299 moles of Fe

<em>Moles Fe₂O₃:</em>

0.299 moles Fe * (2 mol Fe₂O₃ / 4 mol Fe) = 0.150 moles Fe₂O₃

<em>Mass Fe₂O₃ -Molar mass 159.69g/mol-:</em>

0.150 moles Fe₂O₃ * (159.69g / mol) =

<h3>23.9g of Fe₂O₃ are produced</h3>
