Unformatted text preview: 4. The standard free energies of formation of solid sodium chloride and of sodium ions and chloride ions are, respectively, -384.0, -261.87 and . Calculate for sodium chloride. Does your calculation agree with the notion that alkali metal salts are extremely soluble in water? 5. Use the following table to estimate the boiling point of carbon disulfide: Hint: What is at the boiling point? 6. Use the table of bond enthalpies to estimate the enthalpy change in the reaction 7. What is the acid dissociation constant of acetic acid at ? The acid dissociation constant at is and the enthalpy change for the dissociation reaction is -0.34kJ/mol.
