Problem- Assume that delta H not and delta S not are independent of temperature and use data to calculate delta G not for each of the following reactions at 250 degrees C. Over what temperature range will each reaction be spontaneous under standard conditions? (a) HCN (g) + 2H2 (g) goes to CH3NH2 (g) (b) 2Cu^+ (aq) goes to Cu (s) + Cu^2+ (aq) (c) CaCl2 (s) + 2HF (g) goes to CaF2 (s) + 2HCl (g)
This is not a problem given in the book, so I just need the full solution of deriving!
