I have been stuck on this CH1 past paper question for too long and I was wondering if anyone could help me with the answers? Thanks!

So the question goes like this (It's quite long, sorry):

(a) Ammonia, which is a very important product in industry, is produced through the Haber process.
Nitrogen+Hydrogen (With high pressure, and an iron catalyst) --> Ammonia (with sulphuric acid) --> Ammonium sulphate

The Haber process can be represented by the following equation:
N2 + 3H2 = 2NH3 -92kJ mol-1

(i) What type of catalyst is iron in the above process?
(ii) For the equilibrium reaction, explain why a lot research has been done to discover a better catalyst.
(iii) Explain why ammonia is being pulled from the equilibrium as it forms.

Thank you

(i) I think the first one is asking whether it's homogenous or heterogenous
(ii) Think of the conditions needed to achieve the reaction and how sustainable it actually is. If you have a high pressure, what type of equipment do you need? How does it impact health and safety?
(iii) If it wasn't taken out as it forms, it is likely that it would turn into the third phase or react with the sulphuric acid. (Think of how the purity of a chemical or compound affects price and profits and effectiveness of fertiliser.)

I was wondering since our upcoming chemistry exams are coming up if people wanted to be part of a chemistry whatsapp revision group. If you are interested either pm me or responded to this message
