Question description
Solid Titanium metal (Ti) reacts with iodine gas to form solid Titanium(III) iodide. The balanced equation is:
2Ti (s) + 3I2(g) –> 2TiI3 (s)
The heat of reaction for this is measured to be: delta H(rxn) = – 839 kJ.
Answer the following questions in regards to the above process:
(a) Is the reaction exothermic or endothermic?
(b) What will be the enthalpy change for 25.00 g of iodine gas?
