Given:
Gof(N2(g)) = 0.0 KJ/mol
Gof(O2(g)) = 0.0 KJ/mol
Gof(NO(g)) = 86.6 KJ/mol
Balanced chemical equation is:
N2(g) + O2(g) ---> 2 NO(g)
ΔGo rxn = 2*Gof(NO(g)) - 1*Gof( N2(g)) - 1*Gof(O2(g))
ΔGo rxn = 2*(86.6) - 1*(0.0) - 1*(0.0)
ΔGo rxn = 173.2 KJ
This is when 1 mol of N2 reacts.
So, for 1.60 mol,
ΔGo rxn = 173.2*1.60 KJ = 277.12 KJ
Answer: 277.12 KJ
