Increase pressure which shifts the equilibrium to the right.
Increase concns N2 and H2 which drives the reaction to the right.
Decrease the volume which drives the reaction to the right.
I don't think increasing T or adding a catalyst (both which are done in commercial production) count here. Increasing T increases the speed of the reaction as does adding a catalyst but the question doesn't ask about speed; only ways to improve the yield.
3. The Haber–Bosch process for fixation of nitrogen is one of the more important chemical reactions ever invented. Without the invention of this process, which is used to make ammonia for fertilizer, the world’s population would not be as large as it is today.
N2(g) + 3H2(g) 2NH3(g)
• List three ways in which the yield of ammonia in the reaction above can be improved for a given amount of H2.
• Additionally, explain the principle behind each method.
