Unformatted text preview: 7. From your graph, calculate S in J/molK. 8. From your graph, calculate H in kJ/mol. 9. Calculate G in kJ/mol for 30C. [ ] (l) O H 8 (OH) O B Na 2 (s) O H 8 (OH) O B Na 2 2 4 5 4 eq 2 4 5 4 2 + + + Results and Discussion: 10. What does the term standard conditions mean? 11. What does the value of G at tell you about K sp at 30 C? 12. Under standard conditions does the solvation reaction favor products or reactants? 13. If G is positive (it should be), why does some of the borax still dissolve at room temperature? (Hint: what is the difference between G and G ?) 14. Does your value for H suggest that the solvation of borax is endothermic or exothermic? 15. Explain why this result is consistent with the observation that more borax dissolved at higher temperatures....
