Misal laju reaksi diibaratkan: Pada percobaan 2 dan 3 sama, beda Jadi orde reaksi terhadap adalah 2. Untuk mengetahui orde kita masukan data-data percobaan 1dan 2 Jadi orde reaksi terhadap adalah 0. Pada perhitungan di atas kita telah menemukan nilai x=0, dan y=2, maka persamaan laju reaksinya adalah: Oleh karena itu, jawaban yang benar adalah B.

Misal laju reaksi diibaratkan: v double bond k open square brackets A close square brackets to the power of x open square brackets B close square brackets to the power of y
