CHAPTER 6 THERMOCHEMISTRY
... a. The ∆H value for a reaction is specific to the coefficients in the balanced equation. Because the coefficient in front of H2O is a 2, 891 kJ of heat is released when 2 mol of H2O is produced. For 1 mol of H2O formed, 891/2 = 446 kJ of heat is released. b. 891/2 = 446 kJ of heat released for each ...
