題組內容

23. (11%) Baking soda (NaHCO₃) is frequently used to make baking products (bread, cookies, cakes, etc.) rise. The underlying chemical reaction is the decomposition of NaHCO₃ into Na₂CO₃:
2 NaHCO₃(s) → Na₂CO₃(s) + H₂O(g) + CO₂(g) (1)

(b) (6%) The standard formation enthalpies \(\Delta H^0_f\) and standard entropy \(S^0\) for each species involved in reaction (1) are listed in the following table. Calculate the enthalpy of reaction \(\Delta H^0_{rxn}\) and the entropy of reaction \(\Delta S^0_{rxn}\) under standard conditions.
