menentukan persamaan laju reaksi, maaf dicoret coret, tolong dibantu ya kak

V = 1/t

Orde A
{[A]2 / [A]1}^x = V2/V1
{0,2 / 0,1} ^ x =( 1/40) / (1/80)
2^x = 2
2^x = 2^1
X = 1

Orde B
{[B]3 / [B]2}^y = V3/V2
{0,2/ 0,1} ^ y = (1/10) / ( 1/40)
2^y = 4
2^y = 2^2
y = 2


Persamaan laju reaksi
V = k [A]^x [B]^y
V = k [A]^1 [B]^2
V =k [A][B]^2
