We are asked to determine the mass of iodine that reacts if 1.61×103 kJ of heat is emitted by the reaction.
We'll use the thermochemical equation to calculate the mass of I2.
Molar mass I2 = 253.8 g/mol
2 Ti(s) + 3 I2(g) → 2 TiI3(s); ΔH˚rxn= -839 kJ.
Titanium reacts with iodine to form titanium(III) iodide, emitting heat, via the following reaction: 2 Ti(s) + 3 I2(g) → 2 TiI3(s); ΔH˚rxn= -839 kJ. Determine the mass of iodine that reacts if 1.61×103 kJ of heat is emitted by the reaction.
