The rate law depicts the effect of concentration on reaction rate. Second mechanism 2NO(g) ⇄ N₂O₂(g) [fast], N₂O₂(g) + O₂(g) → 2NO₂(g) [slow] is most reasonable. Thus, option b is correct.
<h3>What is rate law?</h3>
Rate law and equation give the rate at which the reaction takes place under the influence of the concentration of the reactants. The balanced chemical reaction is given as,
2NO(g) + O₂(g) → 2NO₂(g)
The rate of the equation is given as,
rate = k [NO]² [O₂]
In a multi-step chemical reaction, the slowest step is the rate-determining step. The second mechanism is given as,
2NO (g) → N₂O₂ (g) [fast]
N₂O₂(g) +O₂(g) → 2NO₂ (g) [slow]
Rate is given as,
rate = k [N₂O₂] [O₂]
Therefore, option b. the second mechanism is the most reasonable.

Doubling the amplitude of a wave means that you increase the energy of a wave factor of quadrupling
Answer:
C. Different heights of holes in the container
Explanation:
The independent variable is the variable that changes. So the independent variable is C because the heights of the holes change.
Answer:
- The limiting reagent is N2O4
- 14,09g
Explanation:
- First, we adjust the reaction.
+ 
⇄
- Second, we assume that the participating moles are equal to the stoichiometric ratios because we do not know the amounts of the reagents.
We can determinate what is the limiting reagent comparing of product amounts which can be formed from each reactant.
Using 
to form 
Using to form 
The limiting reagent is N2O4, because can produce only 0, 783 mol of H2O.
This is the minimum measure can be formed of each product.
∴ 
The answer is D: Salt and Water
