🤓 Based on our data, we think this question is relevant for Professor Robinson & Ye's class at IU.

Solution: The ΔHf˚ of TiI3(s) is –328 kJ/mol and the ΔH˚ for the reaction Ti(s) + 3 I 2(g) → 2 TiI3(s) for the reaction is –839 kJ{ m kJ}. Calculate the ΔH of sublimation of I2(s), which is a solid at 25˚C.
