reactions are reactions in which the products can react to form the reactants. They are represented using a
. The ratio of reactants to products can be changed by changing the
. Reversible reactions that are exothermic in one direction are
in the other direction. When the rate of the forward reaction and the rate of the backward reaction are equal, the reaction is
.
The Haber process is used to produce
out of hydrogen (from
) and nitrogen (from
. These are passed over a catalyst made of
at a temperature of around
°C, and at a pressure of around
atmospheres. The nitrogen and hydrogen react to form ammonia, which is liquefied to separate it out, and then leftover hydrogen and nitrogen are recycled into the system.
