the haber process is a
reversible
reaction of
nitrogen
and
hydrogen
to produce ammonia at
200
atp and at
450
degrees using
iron
as a catalyst
nitrogen is from the
fractional distillation
of
air
hydrogen is obtained byy reacting
methane
with
steam
you collect ammonia by
cooling
it
conditions to increase yeild
cooler
temperatures will shift the reaction to the
right
but it will
slow
down the rate
using an
iron
catalyst ( no effect on
equilibrium
)
increase
pressure
shifts the reaction to the right but really high temperatures are
dangerous
and
expensive
the forward reaction of the haber process is
exothermic
