Calculate the enthalpy of reaction ($\Delta H$) using bond energies or Hess's Law.

1972 was a year that tested the "spontaneity" of reactions before the term "Gibbs Free Energy" was as ubiquitous in high school classrooms as it is today. Predicting the sign of ΔScap delta cap S (entropy) and ΔHcap delta cap H (enthalpy). The Answer Key Logic: If a gas is produced from solids, ΔScap delta cap S is positive (disorder increases). If the reaction vessel gets hot, ΔHcap delta cap H is negative (exothermic). 1972 ap chemistry free response answers
