Studied by 0 peoplewhat is the reaction for the haber process? (including state symbols)
N2(g) + 3H2(g) ↔ 2NH3(g) (+heat)
where is the nitrogen obtained from?
the air, which is 78% nitrogen
where is the hydrogen obtained from?
hydrocarbons from sources such as natural gas or crude oil
does the reaction reach equilibrium?
yes - it is a reversible reaction
what conditions is ammonia made at? (pressure and temperature)
•200atm
•450 degrees
which side of the reaction do higher pressures favour?
forward reaction (4 moles on the left and 2 moles on the right)
is the forward reaction exothermicor endothermic?
exothermic
what will happen to the position of equilibrium if the temperature is increased?
it will move the wrong way (to the left) so the yield of ammonia is greater at lower temperatures
do lower temperatures affect the rate of reaction?
yes - they lower it
is ammonia formed as a gas, a liquid or a solid?
gas - as it cools it liquefies and is removed
what does the iron catalyst do to the reaction?
makes it go faster but doesn’t affect the position of equilibrium
what would happen if the catalyst wasn’t there?
the temperature would have to be raised even further to get a quick enough reaction and that would reduce the percentage yield
