Abstract AR
تم قياس معدل الهدرجة القاعدية لـ (ايثيلوكساليت البوتاسيوم) مع وجود سلفات البوتاسيوم و الصوديوم عند درجات حرارة مختلفة.
و أبانت الدراسة الأثر الإيجابي للملح على غرار ما ورد في نظرية برونستد-ديباي-هكل.
كما توافق أثر الشدة الأيونية (I) على ثابت التغيير (k) مع النظرية.
و قد قمنا كذلك بحساب العديد من ثوابت التنشيط الديناميكية الحرارية، و ظهر لنا اعتماد كل من طاقة التنشيط (E)، و التغير في تنشيط (∆H^#) الانثلبي، و التغير في تنشيط (∆S^#) الفوضوي على شدة الوسط الأيونية.
Abstract EN
The rates of alkaline hydrolysis of potassium ethyloxalate have been measured in the presence of sodium and potassium sulfate at various temperatures.
A positive salt effect has been found in accordance with the Bronsted–Debye–Huckel theory.
The effect of ionic strength (I ) on the rate constant (k) is in good agreement with the theory.
Various thermodynamic activation parameters have been calculated.
It is shown that the energy of activation (E), change in enthalpy of activation (ΔH# ), and change in entropy of activation (ΔS# ), are all dependent on the ionic strength of the medium
