Using the following thermochemical equations;

(a) CaO (s) + Cl₂ (g) → CaOCl₂ (s) ΔH°= -110.9 kJ
(b) CaO (s) + H₂O (l) → Ca(OH)₂ (s) ΔH°= -65.1 kJ
(c) H₂O (l) + CaOCl₂ (s) + Br₂ (l) → Ca(OH)₂ (s) + Br₂ (l) +2 NaCl (s) ΔH°= -60.2 kJ

Determine the value of ΔH° in kJ for the following reaction:

½ Cl₂ (g) + NaBr (s) → ½ Br₂ (l) + NaCl (s)
