Use bond energies, values of electron affinities, and the ionization energy of hydrogen (1312 kJ/mol) to estimate ΔH for each of the following reactions:
(a) HI(g) → H⁺(g) + I⁻(g)
(b) HBr(g) → H⁺(g) + Br⁻(g)
(c) HCl(g) → H⁺(g) + Cl⁻(g)
(d) H₂O(g) → H⁺(g) + OH⁻(g)
(Electron affinity of OH⁻(g) = -180 kJ/mol)
