Answer:
An object which experiences either a change in the magnitude or the direction of the velocity vector can be said to be accelerating. This explains why an object moving in a circle at constant speed can be said to accelerate - the direction of the velocity changes.

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.

Answer:
0.033 M
Explanation:
From the question given above, the following data were obtained:
Volume of stock solution (V1) = 250 mL
Molarity of stock solution (M1 ) = 0.10 M
Volume of diluted solution (V2) = 750 mL
Molarity of diluted solution (M2) =.?
Thus, we can obtain the molarity of the diluted solution by using the dilution formula as illustrated below:
M1V1 = M2V2
0.1 × 250 = M2 × 750
25 = M2 × 750
Divide both side by 750
M2 = 25/750
M2 = 0.033 M
Therefore, the molarity of the diluted solution is 0.033 M.
