The following balanced equation shows the formation of. Jan 06, 2016В В· Here's how that would look like. Start by having a look at the thermochemical equation the problem provides you with "N"_text(2(g]) + 3"H"_text(2(g]) -> 2"NH"_text(3(g]), " "DeltaH_text(rxn) = -"100.3 kJ" The important thing to notice here is that the enthalpy change of reaction, DeltaH_"rxn", carries a negative sign. What that means is that when nitrogen gas and hydrogen react to form ammonia, Here nitrogen gas and oxygen gas combines together to form a single product i.e,the ammonia.Therefore it is an example of combination reaction.Hea is evolved in this reaction and it is an exothermic reaction.This reaction is also used in industries to produce ammonia and known as Haber process..
