Data percobaan reaksi: A + 2B → AB2, menunjukkan bahwa apabila konsentrasi A dinaikkan 2 kali sedang konsentrasi B tetap, laju reaksinya naik 2 kali. Bila konsentrasi A tetap dan konsentrasi B dinaikkan 2 kali, maka laju reaksinya naik 2 kali pula. Persamaan laju reaksinya dapat dituliskan
r = k [A]2 [B]3
r = k [A]2 [B]2
r = k [A] [B]2
r = k [A]2 [B
r = k [A] [B]

Berikut adalah data percobaan reaksi: A2 + 2C→ 2AC
Persamaan laju reaksi untuk reaksi tersebut adalah
r = k [A2][C]
r = k [A2]0[C]2
r = k [A2][C]2
r = k [A2]2[C]
r = k [A2][C]0
