At this point of advancements in science, chemists have a good understanding of the kinetics of reactions. They can predict the effects of changes in pH, temperature, and concentration in chemical reactions.
In a cylinder, there is a reaction mixture of hydrogen and iodine. The hydrogen and the iodine react to form hydrogen iodide.
The industrial production of ammonia is done by a process called Haber process. The reaction occurs as shown below, and is usually done in the presence of an iron catalyst.
DH = –92kJ
