Haber Process Flashcards
1
Q
what makes ammonia?
A
nitrogen + hydrogen
2
Q
where does nitrogen come from?
A
air
3
Q
where does hydrogen come from?
A
natural gas
4
Q
conditions needed for haber process? (temp, pressure, catalyst)
A
temp = 450 degrees celcius? pressure = 200 atm catalyst = made from iron
5
Q
what is a catalyst?
A
something that increases the rate of reaction by lowering the activation energy by creating a short cut and doesn’t get used up.
6
Q
what is the forward reaction in the haber process
A
exothermic
7
Q
what is the backward reaction in the haber process
A
endothermic
8
Q
what happens to the yield if the temperature is higher or lower than 450 degrees?
A
higher = lower yield lower = too slow, too low ror
9
Q
what happens to the yield if the pressure is higher or lower than 200 atm?
A
higher = too expensive in energy + money lower = too slow, poor yield
10
Q
what affect does the iron catalyst have on equilibrium?
A
none bc ror forward and backward increase at same amt
