Jika konsentrasi A dinaikan tiga kali pada konsentrasi B tetap, laju reaksi menjadi sembilan kali lebih cepat. Jika A dan B dinaikan tiga kali, laju reaksi menjadi 27 kali lebih cepat. Persamaan laju reaksinya adalah...
a. V = k [A]² [B]
b. V = k [A] [B]²
c. V = k [A] [B]
d. V = k [NO]
e. V = k [A]
a. V = k [A]² [B]
b. V = k [A] [B]²
c. V = k [A] [B]
d. V = k [NO]
e. V = k [A]

Orde [A]
V₁/V₂ = K₁/K₂ × [B/B]^X × [A/3A]^Y
V/9V = [A/3A]^Y
1/9 = [1/3]^Y
(1/3)² = [1/3]^Y
Y = 2
Orde [B]
V₂/V₃ = K₂/K₃ × [B/3B]^X × [3A/3A]^Y
9V/27V = [B/3B]^X
1/3 = [1/3]^X
(1/3)¹ = [1/3]^X
X = 1
Maka, persamaan laju reaksinya,
V = K [A]² [B]
