8.000 moles of H2(g) reacts with 4.000 mol of O2(g) to form 8.000 mol of H2O(l) at 25 °C and a constant pressure of 1.0133 bar. If 546.4 kJ of heat are released during this reaction, and PΔV is equal to -29.60 kJ, then:

▸ ΔH° = +546.4 kJ and ΔU = +576.06 kJ

▸ ΔH° = +546.4 kJ and ΔU = +516.8 kJ

▸ ΔH° = -546.4 kJ and ΔU = -516.8 kJ

▸ ΔH° = -546.4 kJ and ΔU = -576.0 kJ
