The equilibrium constant for the reaction of NH3 (aq) + H2O ⇌ NH+4 + OH- is Kb = 1.479 × 10-5 at 5°C 1.570 × 10 -5 at 10oC
(a) Assuming ∆H° and ∆S° are constant in the interval 5° - 10°C (probably a good assumption for small ∆T ), use Equation 6-8 to find ∆H° for the reaction in this temperature range.
(b) Describe how Equation 6-8 could be used to make a linear graph to determine ∆H°, if ∆H° and ∆S° were constant over some temperature range.
