f all the N2
and H2
are consumed, what volume of NH3
, at the same temperature and pressure, will be produced?
The balanced chemical equation for the reaction between N2 and H2 to produce NH3 is:
N2 + 3H2 -> 2NH3
From this equation, we can see that 1 mole of N2 reacts with 3 moles of H2 to produce 2 moles of NH3.
Since we are given that all the N2 and H2 are consumed, the limiting reactant in this case will be the one that is completely used up first. In this case, N2 will be completely consumed first because for every mole of N2, 3 moles of H2 are needed for the reaction.
Therefore, for every mole of N2 consumed, 2 moles of NH3 are produced.
Given that the volume of gases is directly proportional to the number of moles, we can say that the volume of NH3 produced will be twice the volume of N2 reacted.
Therefore, if V is the volume of N2 consumed, the volume of NH3 produced will be 2V.
