(there's a problem in this question that I had to find. The answer was given to me... the final answer should could out to -75.2 kJ/mol. Just need to find out how I get to that answer, the work)
The chemical equation is…
N2 (g) + 3H2 (g)—> 2NH3 (g)
Using the S^0 values, and calculate the (▲H^0f) for the formation of ammonia.
Substance_______(S^0)____________2(H^0f)
N2 ____________191.5_____________0.0
3H2____________3(130.6)=391.8_____0.0
2NH3___________2(192.5)=385______2(-46.2)= - 92.38
