haber process Flashcards
1
Q
what is the formula for the haber process
A
N2 + 3H2 —> 2NH3
2
Q
what pressure is optimal for haber process
A
a pressure of 200 atmospheres
3
Q
what temperature
A
450°C
4
Q
what catalyst
A
iron catalyst
5
Q
is the haber process endo or exothermic
A
it is exothermic as it makes bonds
6
Q
why is the temperature compromised
A
it must be low enough to achieve a reasonable equilibrium yield but high enough to achieve a reasonable rate of reaction. the iron catalyst also works more efficiently at temperatures over 400°C
