The reaction between hydrogen and oxygen to yield water vapor has delta H+ -484kJ: 2H2(g)+O2(g)-->2H2O(g) delta H=-484 kJ Part A How much PV work is done in kilojoules for the reaction of 0.20 mol of H2 with 0.10 mol of O2 at atmospheric pressure if the volume change is -3.2L ? Express your answer using two significant figures. Part B What is the value of delta E in kilojoules
