Given:
Gof(HBr(g)) = -53.45 KJ/mol
Gof(H2(g)) = 0.0 KJ/mol
Gof(Br2(l)) = 0.0 KJ/mol
Balanced chemical equation is:
2 HBr(g) ---> H2(g) + Br2(l)
ΔGo rxn = 1*Gof(H2(g)) + 1*Gof(Br2(l)) - 2*Gof( HBr(g))
ΔGo rxn = 1*(0.0) + 1*(0.0) - 2*(-53.45)
ΔGo rxn = 106.9 KJ
This is when 2 mol of HBr reacts as per given chemical equation.
For 1.84 moles of HBr, ΔGo rxn = 106.9 * 1.84 / 2 = 98.35 KJ
Answer: 98.35 KJ
