Assume that H and S are independent of temperature and use data in Appendix 2A to calculate

Question:

Assume that ΔH° and ΔS° are independent of temperature and use data in Appendix 2A to calculate ΔG° for each of the following reactions at 250. °C. Over what temperature range will each reaction be spontaneous under standard conditions? (a) 2 NO(g) + O(g) 2 NO(g) (b) CaO (s) + HO(1) (c) CaC(s) + 2 HO(1) Ca(OH) (s) Ca(OH)(aq) + CH(g) 2A THERMODYNAMIC DATA AT 25 C Inorganic Substances Substance Aluminum Al(s) Al+ (aq) Al(OH)3(S) AlO3(s)
