if so, please could you explain? thanks!
yep! the haber process is important for C2! it's quite simple really... n2 + 3h2 <=> 2nh3
it's the production of ammonia, just remember that high pressure favours forward reaction, lower temp gives greater yiled due to forward reaction being exothermic and it is a reversible reaction!
yep n u cud get a siz mark question on it e.g describe conditions used in the harber process and why are these chosen??
i ment six mark question
If you do get a long question on the Haber process, it may be beneficial to mention that the conditions used are a compromise.
Too high pressure is expensive and dangerous (more risk of explosion)
Low temperature = high yield, but it takes ages
High temperature = low yield, happens quickly.
Remember that increasing pressure favours the side with the fewest molecules.
Increasing temperature favours the endothermic side, and decreasing temperature favours the exothermic side.
Remember that the forward reaction is exothermic (heat is given out)
The backward reaction is endothermic (heat is taken in)
I think that's the gist, it has been a year since I did GCSE Chemistry.
oh forgot to say that i'm doing the new aqa specification from 2011 onwards, i dont think i need it but thanks very much!
To be on the safe side you could go onto the AQA website and check your specification.
