The values are given in the table below

substance δh°f (kj/mol)
so2 (g) −297
so3 (g) −396
so2cl2 (g) −364
h2so4 (ℓ) −814
h2o (ℓ) −286

the value of δh° for the following reaction is −62.1 kj. what is the value of δh°f for hcl(g)?

so2cl2(g) + 2 h2o(ℓ)→ h2so4(ℓ) + 2 hcl(g)

ΔH°f,HCl = - 92.05 KJ/mol

Explanation:

∴ ΔH°rxn = 62.1 KJ/mol

⇒ - 62.1 KJ/mol = 2 ΔH°f,HCl(g) + ΔH°f,H2SO4(l) - 2 ΔH°f,H2O(l) - ΔH°f,SO2Cl2(g)

⇒ 2 ΔH°f,HCl = - 62.1 KJ/mol + 2 ΔH°f,H2O(l) + ΔH°f,SO2Cl2(g) - ΔH°f,H2SO4(l)

⇒ 2 ΔH°f,HCl = - 62.1 KJ/mol + 2 (-286 KJ/mol) - 364 KJ/mol - (- 814 KJ/mol)

⇒ 2 ΔH°f,HCl = - 62.1 KJ/mol - 572 KJ/mol - 364 KJ/mol + 814 KJ/mol

⇒ 2 ΔH°Δf,HCl(g) = - 62.1 KJ/mol - 122 KJ/mol

⇒ 2 ΔH°f,HCl(g) = - 184.1 KJ/mol

⇒ ΔH°f,HCl(g) = ( - 184.1 KJ/mol ) / 2 = - 92.05 KJ/mol
