1. The problem statement, all variables and given/known data Is the reaction for the production of ammonia an endothermic reaction or an exothermic reaction? Explain. 2. Relevant equations n/a 3. The attempt at a solution I know that the production of ammonia in the Haber process is indeed exothermic and that the backwards reaction (NH3 -> N2 + H2) is endothermic, because I saw this when I was reading through Le Chatelier's principle, but I still am not sure why it is exothermic. Is it because the bonding between hydrogen and nitrogen releases energy? But even if that was true it's not detailed enough to answer the question, is it?
