Chapter 9, Problem 9.3P

PRACTICE 9.3 The reaction between hydrogen and oxygen to yield water vapor has $\Delta H$ = -484 kJ. How much PV work is done, and what is the value of A£ in kilojoules for the reaction of 2.00 mol of H₂ with 1.00 mol of O₂ at atmospheric pressure if the volume change is -24.4 L?

$\text{2}{H}_2(g)+O_2(g)\to {\text{2H}}_{\text{3}}\text{O(g)}$

$\Delta H°$ = -484 kJ
