Berikut ini adalah data hasil percobaan laju reaksi dari reaksi :
2NO(g) + 2H2(g) → N2(g) + 2H2O(g) (l)
Pada suhu dan tekanan tertentu diperoleh data eksperimen seperti pada tabel berikut :
Maka persamaan laju reaksinya dapat dinyatakan .....
V = k [NO]2
V = k [NO]2 [H2]
V = k [H2]
V = k [NO]2 [H2]2
V = k [NO] [H2]
