Explanation:
Given that:
2H₂(g) + 2NO(g) → 2H₂O(g) + N₂(g)
Experiment [H₂] (M) [NO] (M) Initial Rate (M/s)
1 0.010 0.025 2.4 × 10⁻⁶
2 0.0050 0.025 1.2 × 10⁻⁶
3 0.010 0.0125 0.60 × 10⁻⁶
The general formula for rate law is:
From (1) and (2), it is obvious that the concentration of NO looks constant unlike that of H₂ which has decreased by 1/2. Similarly, the initial rate also reduced by 1/2. Hence, the initial rate is proportional to the concentration of H₂. So, x = 1
Also;
From (1) and (3), it is obvious that the concentration of H₂ looks constant unlike that of NO which has decreased by 1/2. Similarly, the initial rate also reduced by 1/4. Hence, the initial rate is proportional to the concentration of NO. So, y = 2
∴
The overall rate law is:
(b)
From (1)
The rate constant is:
∴
k = 0.38 / M².s
(c)
From the rate law, it is pertinent to understand that the slow step in the reaction includes one molecule of H₂ and two molecules of NO, where O atoms serve as an intermediary.
SO;
H₂ + 2NO → N₂ + H₂O + O slow step
O + H₂ → H₂O fast step
2H₂ + 2NO → 2H₂O + N₂

Explanation:
To determine limiting reactant divide mole quantities of reactants by the respective coefficient in the balanced equation. The smaller value is the limiting reactant.
P₄ + 5O₂ => 2P₂O₅
12/1 = 12 15/5 = 3
O₂ is the limiting reactant. P₄ will be in excess when rxn stops.
Answer:
Explanation:
Hello,
In this case, for the given combustion process, we can compute the present moles of carbon atoms by considering that the only product containing carbon is CO2, thus, we have:
Next, we compute the moles of hydrogen that is present at the water only as a product:
Then, we compute the moles of oxygen by considering the oxygen present in both the CO2 and H2O and the initial sample:
Now, we divide the moles of C, H and O by the moles of O since they are lower amount, in order to compute the subscript in the empirical formula:
But the smallest whole number is:

1:3
The ratio of Al3+ ions to Cl− ions in the chemical formula is 1:3.

False. It is not fractional distillation.
