1. Who developed the Haber Process?
When? What country was he from?
The Haber Process is a very important process indeed, it
was invented by a german chemist by the name of fritz
haber in the ealry 20th century during world war 1.
2. Write a balanced chemical equation for
this reaction, including the energy term. Is
it an
endothermic or exothermic reaction?
Below I have here an example of a
balanced chemical equation for the Haber
process:
N2 + 3H2 => 2NH3
this reaction is exothermic
The Haber Process is a method of
creating ammonia from nitrogen and
hydrogen using iron as a catalyst, under a
certain temperature and pressure.
3. Use Le Châtalier’s Principle to explain the
conditions that favour the forward reaction.
4. Temperature is important in regulating
this reaction. Is the reaction carried out at
high or low
temperatures? How does this relate to part
of your answer for Question 3?
5.Under what temperature and pressure
conditions is this reaction typically carried
out?
N2 + 3H2 => 2NH3
This equation favors the forward reaction, so more ammonia will in the
end be produced therefore in this equation we want the equilibrium to
be on the right. A person could add more N2 or H2 doing so would
raise the reacANT concentrations and would force the system to
breakdown or take in the added reactant to re-establish equilibrium
once again. Because N2 is found in air, it is a great reactant to use to
re-adjust equilibruiim. This equation being exothermic just means that
by reducing the temperature would make it favor the forward in return
producing ammonia, increasing the temp, would do the complete
opposite favouring the reverse, and consuming instead of producing
ammonia. Meaning this is working on low temp.(room temp)
6. What catalyst is used for this
reaction?
An iron catalyst is used to increase the rate of the
reaction while it is at room temperature without the
equilibrium being affected. In return this will not make
more NH3, but it does increase the rate of the reaction
as I said.
7. a) Provide a short paragraph providing
some historical background. B)Why was
this an important chemical process?
8. Is the Haber Process still important
today? Explain.
The Haber Process is a method of
producing ammonia developed in WWI. The Germans
needed nitrogen for making their explosives during world war
1. When the Allies blocked off all trade routes going to and from
Germany, they lost all sources of sodium nitrate and potassium
nitrate, which was their source of nitrogen. So they were forced
to find an alternate source of nitrogen, they went to the air, the
nitrogen they found was 80% nitrogen!! Mr. Fritz Haber being a
chemist developed the Haber Process in WWI, as was
mentioned earlier in my presentation, “which takes
molecular nitrogen from the air and combines it with
molecular hydrogen to form ammonia gas, which the chemical
formula is NH3”
The reason for this being an important
process (for the Germans) is because it
gave them an alternaate source of nitrogen
therefore continuing the process of their
explosives. Which were halted when their
supplies and such were blocked from
entering or exiting germany.
“The Haber process is important today
because the fertilizer generated from
ammonia is responsible for sustaining onethird of the Earth's population.” Now I’m no
genius but one third of the worlds
population sounds like a lot of people
right? Absolutely correct!! And I think just
that alone should answer the big question “
is the haber process still important today?”
of course it is.
So yeah, thanks for watching my presentation, I
hope it gave you a little more information about
the haber process and it’s creator, that you didn’t
know before, so yeah, thanks 
