The Value of ΔR,SΔH° and ΔR,SΔS° of Three Antihistamines
| Compound | Doxylamine | Cetirizine | Hydroxyzine |
|---|---|---|---|
| ΔR,SΔH° (kJ mol−1) | −0.365 | −0.141 | −0.166 |
| ΔR,SΔS° (J mol−1) | −1.138 | −0.218 | −0.473 |
| The regression equation | ln α = 365.79/T – 1.1407 (r = 0.9978) | ln α = 140.75/T – 0.2180 (r = 0.9993) | ln α = 166.55/T– 0.4732 (r = 0.9994) |
