Question

Calculate the enthalpy of formation of HCl (g) at 1450 K and 1 bar pressure, given that

o Hf

 [HCl,g] = – 92.3 kJ/mol at 298 K and

Cp,m(H2

,g) = [29.06 – 0.8363 × 10–3 T + 20.11×10–7 T2

] J/k mol

Cp,m(Cl2

,g) = [39.69 + 10.14 × 10–3 T – 40.37 ×10–7 T2

] J/k mol

Cp,m(HCl,g) = [28.16 + 1.81 × 10–3 T + 15.46 ×10–2 T2

] J/k mol

Over the temperature range of 298 K to 1450 K​
