Manipulating Thermochemical Equations
When 2 mol H_2(g) and 1 mol O_2(g) react to give liquid water, 572 kJ of heat evolves.
2H_2(g) + O_2(g) → 2H_2O(l ); ΔH = – 572 kJWrite this equation for 1 mol of liquid water. Give the reverse equation, in which 1 mol of liquid water dissociates into hydrogen and oxygen.
