Question
In the Haber's process for the industrial manufacture of ammonia, finely divided iron is used as a heterogeneous catalyst alongside molybdenum acting as a promoter. According to standard optimized industrial conditions, what is the strictly maintained pressure for this process in $\text{bar}$?
💡 Solution & Explanation
The Haber's process ($N_2 + 3H_2 \rightleftharpoons 2NH_3$) utilizes Le Chatelier's principle. To maximize the yield of ammonia, high pressures and moderate temperatures are required alongside the Fe catalyst. The standard industrial conditions are heavily specified as a pressure of $200\text{ bar}$ and a temperature between $723\text{ K}$ and $773\text{ K}$.
