Abstract
The heat of reaction for SnJ2 (c)+J2 (c)+4045 CS2 (l)=[SnJ4; 4045 CS2] (sol) has been determined to be (−41.12±0.55) kJ mol−1, [(−9.83±0.13) kcal mol−1] by isoperibol solution calorimetry. Combining this result with the heat of formation of SnJ4 in CS2 determined in a previous investigation11 the value (−153.9±1.40) kJ mol−1, [(−36.9±0.33) kcal mol−1] has been derived for the heat of formation, ΔH f ι (SnJ2;c; 298.15 K), of tin diiodide.
