<u>Ans: O2 because it produces only 0.20 mol of NO</u>
<u>Given:</u>
Mass of NH3 = 4.0 g
Mass of O2 = 8.0 g
<u>To determine:</u>
The limiting reagent in the given reaction
4NH3 + 5O2 → 4NO + 6H2O
<u>Explanation:</u>
# moles of NH3 = 4.0/17 g.mol-1 = 0.2353 moles
# moles of O2 = 8.0/32 = 0.25 moles
Based on the reaction stoichiometry:
1 mole of NH3 produces 1 mole of NO
Therefore, 0.2353 moles of NH3 will produce: 0.2353 moles of NO
Similarly, 1 mole of O2 will produce 4/5 moles of NO
0.25 moles of O2 will form: 0.25*4/5 = 0.2 moles of NO
Thus, O2 is the limiting reactant.
Answer:
P and N directly or inversely proportional
Charles' law states that volume (V) and temperature (T) are directly proportional. Gay-Lussac's law states that pressure (P) and temperature (T) are directly proportional. Avagadro's law states that the amount (n) of a substance is directly proportional to the volume (V)

Explanation:
Hello,
In this case, for the given information, we can compute the rate of disappearance of NO₂ by using the following rate relationship:
Whereas it is multiplied by the the inverse of the stoichiometric coefficient of NO₂ in the reaction that is 2. Moreover, the subscript <em>f</em> is referred to the final condition and the subscript <em>0</em> to the initial condition, thus, we obtain:
Clearly, it turns out negative since the concentration is diminishing due to its consumption.
Regards.
