How much ammonia is produced if 1.80 m3 of hydrogen reacts with 0.5m3 of nitrogen? Also state which reagent is in excess and by how much?
Question is related to the Haber process. Please can anyone answer this for me by 02 July 2010.
Thanx

First write the balanced reaction.

3H2 + N2 => 2 NH3

If the reaction were stoichiometric, there would be three times as many moles of H2 as N2. That also means three times the volume.

In your case, there are more than 3 times as many moles of H2 as N2.

It should be obvious which reactant is in excess, and by how much.

1.0 m^3 of NH3 will be formed, when the products are brought to the pressure and temperature of the reactants. If you know P and T, you can also state the number of moles formed. There are 22.4 liters per mole at STP.
