Haber Challenge
N3C
- Chemical Equation
- N (g)+3H (g) = 2NH (g) (+heat)
- N (g)+3H (g) = 2NH (g) (+heat)
- Haber Process diagram
- Raw Materials
- Nitrogen
- Obtained easily from the air
- Obtained easily from the air
- Hydrogen
- Obtain from natural gas or cracking hydrocarbons
- Obtain from natural gas or cracking hydrocarbons
- Nitrogen
- Structure and Bonding
- Ammonia
- Has a trigonal pyramidal
shape which has no charge. It
is a Simple covalent structure
that has a low melting and
boiling point as not a lot of
energy is needed to break the
bonds. They have a fixed size
and the forces of ascttraction
between the molecules are
weak intermolecular forces.

- Nitrogen
- It is a non- metal with 5
electrons in it's
outer-shell.The bonds are
very strong
- It is a non- metal with 5
electrons in it's
outer-shell.The bonds are
very strong
- Hydrogen
- Non- metal with one electron
in its outer-shell.
- Non- metal with one electron
in its outer-shell.
- Ammonia
- Operating Conditions
- Increase in temp
- Decreases the yield of ammonia as it
moves the reaction in an endothermic
reaction which in this case is the
backwards reaction
- Increase the rate as the molecules have more energy so
therefore move faster meaning they collide with more
force and more often
- Decreases the yield of ammonia as it
moves the reaction in an endothermic
reaction which in this case is the
backwards reaction
- Increase in pressure
- The amount of ammonia increases as the reaction moves
in the direction of the least number of molecules, in this
case the reaction moves in the forward direction
- speeds up the rate at which the equilibrium is reached as the
number of particles in the same volume is increases therefore
there are more collisions per second
- The amount of ammonia increases as the reaction moves
in the direction of the least number of molecules, in this
case the reaction moves in the forward direction
- Adding a catalyst
- there is no affect od the
amount of ammonia
produced
- Increases the rate at which
equilibrium is increased as
it provides an alternative
route of lower activation
energy
- there is no affect od the
amount of ammonia
produced
- Increase of nitrogen concentration
- increases the yield of ammonia as it
unbalances the equilibrium so the reaction
moves in the forward direction in order to
remove the excess nitrogen
- Increase the rate as more nitrogen
particle are in the same volume hence
more collisions per second
- increases the yield of ammonia as it
unbalances the equilibrium so the reaction
moves in the forward direction in order to
remove the excess nitrogen
- Increase in temp
- Chemical tests
- How to make 30,000 tons a year
- N +3H = 2NH
- 30,000 tons of 2NH needs
24706 tons of nitrogen &
5294.1 tons of hydrogen
- 30,000 tons of 2NH needs
24706 tons of nitrogen &
5294.1 tons of hydrogen
- N +3H = 2NH
- Hydrogen gas
- If you put lit splint over hydrogen
gas it will make a squeaky pop
- If you put lit splint over hydrogen
gas it will make a squeaky pop
- Ammonia
- turns damp litmus paper blue
- turns damp litmus paper blue
- Nitrogren
- Will put out a

- Uses of product
- Fertiliser, bleach, paper pulp,
pharmaceuticals, explosives
- Fertiliser, bleach, paper pulp,

- Reaction Energetics
- An exothermic reaction
- Enthalpy Change calculations
450 x 4.18 x 30,000 =31,350,000
31,350,000/20= 1,5667,500
