What is the equilibrium expression for the reaction below?
1 answer:
Answer:
A.
Explanation:
Hello there!
In this case, for us to figure out the appropriate equilibrium expression, it will be firstly necessary for us to recall the law of conservation of mass which states that the equilibrium constant of an equilibrium chemical reaction is written by dividing the products and reactants and including the stoichiometric coefficients as exponents. In such a way, for the given reaction, we will have:
As N2O is the product whereas N2 and O2 are reactants; thus, the equilibrium expression will be A.

Answer:
3.6 mol H₂
Explanation:
- N₂ + 2H₂ → 2NH₃
In order to convert from N₂ moles to H₂ moles we need to use a conversion factor. This conversion factor has to have<u> N₂ moles in the denominator and H₂ moles in the numerator</u>, using the <em>stoichiometric coefficients</em> of the reaction, as follows:
- 1.8 mol N₂ *
= 3.6 mol H₂
