Mass of H₂ needed to react with O₂ : 1.092 g
<h3>Further explanation</h3>The concentration of a substance can be expressed in several quantities such as moles, percent (%) weight / volume,), molarity, molality, parts per million (ppm) or mole fraction. The concentration shows the amount of solute in a unit of the amount of solvent.
Reaction
O₂(g) + 2H₂(g) → 2H₂O(g)
mass of O₂ : 8.75 g
mol O₂(MW=32 g/mol) :
From the equation, mol ratio of O₂ : H₂ = 1 : 2, so mol H₂ :
Mass H₂ (MW=2 g/mol) :
Answer:
The forward reaction is occurring at a faster rate than the reverse reaction.
Explanation:
Reaction quotient (Q) of the given reaction is -
where [NO], and
represents concentrations of respective species at a certain time.
Here = 0.80 M,
= 0.050 M and [NO] = 0.10 M
So,
Hence
It means that forward reaction is faster than reverse reaction at that point. Because then only concentration of NO is higher than concentrations of and
which makes Q higher than K.
