Predict the sign of the entropy change for each of the followingprocesses and give your reasoning why:
1. Solid sugar is added to water to form a solution.
2. Iodine vapor condenses on a cold surface to formcrystals.
3. N2(g) + 3H2 (g) 2NH3(g)
4. H2O(l) H2O(g)
5. CaCO3(s) CaO(s) +CO2(g)
6. NH4NO3(s) +H2O(l) NH4+ (aq)+ NO3- (aq)
7. freezing of water  Â
8. boiling of water
9. crystallization of salt from a supersaturated solution
10. the reaction 2 NO(g) → N2O2(g)
11. the reaction 2 H2(g) + O2(g) → 2 H2O(g)
12. Fe(s) → Fe(l)  Â
13. 2 Fe(s) + 3/2 O2(g) → Fe2O3(s)  Â
14. HF(l) → HF(g)
15. 2 H2O2(l) → 2 H2O(l) + O2(g)
16. H2O(l) -> 2 H2(g) + O2(g)
17. CO(g) + 3 H2(g)-> CH4(g)+ H2O(g)
18. 2 NaHCO3(s) --->Na2CO3(s) + H2O(g) +CO2(g)
19. CO(g) + H2O(g) ----> CO2(g) +H2(g)
20. CaCO3(s) ----> CaO(s) + CO2(g)
21. 2NH3(g) + CO2(g) ---->NH2CONH2(aq) + H2O(l)
22. 2Na2O2(s) + 2H2O(l) --->4NaOH(aq) + O2(g)
23. C2H5OH(l) + 3O2(g) --->2CO2(g) + 3H2O(g)
Plz let me know how you did it.
Simple description is the best
Thanks
