1- ΔG is of great magnitude, the reaction goes virtually to completion and is essentially irreversible
اذا جانت ال دلتا جي سالبه و كُلش عاليه ف عندي هواي طاقه ويكون تفاعل غير انعكاسي
2- ΔG is great, the system is stable, with little or no tendency for a reaction to occur
هنا اذا جانت دلتا جي موجبه بس عاليه حتكون مستقره وماكو اي تفاعل يصير
3- If ΔG is zero, the system is at equilibrium and no net change takes place
اما اذا جانت دلتا جي صفر ف تكون متساويه وبدون أي تغييرات
*concentrations of 1.0 mol/L, ΔG0 is the standard free energy change
اما داخل جسم الإنسان ف ال standard ph=7
