As shown below, the combustion reaction that occurs between hydrogen gas and oxygen gas produces water and 485 kJ of heat. What does this information reveal about the heat transfer that will occur when water decomposes into hydrogen gas and oxygen gas? 2 H2 (g) + 1 O2 (g) → 2 H2O (g) ΔHrxn = -485 kJ
