question 20

Multiple Choice

When 6.000 moles of H₂(g) reacts with 3.000 mol of O₂(g) to form 6.000 mol of H₂O(l) at 25°C and a constant pressure of 1.00 atm.If 409.8 kJ of heat are released during this reaction,and PΔV is equal to -22.20 kJ,then

• A)ΔH° = +409.8 kJ and ΔE° = +432.0 kJ.
• B)ΔH° = +409.8 kJ and ΔE° = +387.6 kJ.
• C)ΔH° = -409.8 kJ and ΔE° = -387.6 kJ.
• D)ΔH° = -409.8 kJ and ΔE° = -432.0 kJ.
