Chapter 5, Problem 71E

The decomposition of hydrogen peroxide, ${\text{H}}_2{\text{O}}_2$, has been used to provide thrust in the control jets of various space vehicles. Using the data in Appendix G, determine how much heat is produced by the decomposition of exactly 1 mole of ${\text{H}}_2{\text{O}}_2$ under standard conditions.

$2{\text{H}}_2{\text{O}}_2\left(l\right)\to 2{\text{H}}_2\text{O}\left(g\right)+{\text{O}}_2\left(g\right)$
