5.3 Exercise 37

Avg difficulty 2.5

The white pigment TiO2 is prepared by the reaction of titanium tetrachloride, TiCl4, with water vapor in the gas phase: TiCl4(g)+2H2O(g)⟶TiO2(s)+4HCl(g).\text{TiCl}_{4} \left(g\right) + 2 \text{H}_{2} \text{O} \left(g\right) \rightarrow \text{TiO}_{2} \left(s\right) + 4 \text{HCl} \left(g\right) .

How much heat is evolved in the production of exactly 1 mole of TiO2(s) under standard state conditions?
