Words and meanings to learn
ammonia
compound with the formula NH₃, made from nitrogen and hydrogen
equilibrium
a state in a reversible reaction where the forward and backward reactions occur at the same rate, meaning the amounts of reactants and products remain constant
Haber process
an industrial process used to make ammonia by reacting nitrogen from the air with hydrogen at high temperature and pressure in the presence of an iron catalyst
nitrogen
a gas (N₂) that makes up about 78% of the air; it is very unreactive because of its strong triple bond and is used in the Haber Process to make ammonia
hydrogen
a very light, reactive gas (H₂) used in the Haber Process; it is commonly produced by reacting methane with steam to form hydrogen and carbon monoxide
