Chapter 5, Problem 75E

The white pigment ${\text{TiO}}_2$ is prepared by the reaction of titanium tetrachioride, ${\text{TiCl}}_4$, with water vapor in the gas phase: ${\text{TiCl}}_4\left(g\right)+2{\text{H}}_2\text{O}\left(g\right)\to {\text{TiO}}_2\left(s\right)+4\text{HCl}\left(g\right)$.

How much heat is evolved in the production of exactly 1 mole of ${\text{TiO}}_2\left(s\right)$ under standard state conditions?
