:في المعادلة التالية
2ClO2(g) + 2OH-(aq) → ClO3-(aq) + ClO2-(aq) +H2O(l)
[OH-] اذا علمت ان معادلة معدل سرعة التفاعل تتناسب طردياً مع
: فان معدل السرعة لهذا التفاعل [ClO2] ومع مربع
rate = K [ClO2]2 [OH-]2
rate = K [ClO2] [OH-]2
rate = K [ClO2]2 [OH-]
rate = K [ClO2] [OH-]

: وفقا للمعادلة التالية (I-) مع ايونات اليوديد (S2O82-) تتفاعل ايونات فوق الكبريتات
S2O82-(aq)+ 3I-(aq) → 2SO42-(aq) + I3-(aq)
،وعند تتبع سير التفاعل، تم الحصول على النتائج التجريبية في الجدول المقابل.
:معادلة معدل سرعة التفاعل هي
rate = K [S2O82-]2 [I-]2
rate = K [S2O82-] [I-]2
rate = K [S2O82-]2 [I-]
rate = K [S2O82-] [I-]
