# Rate Law Based on Data

APCHEM-GESISA

Given the following reaction:

$$2A + B + C \rightarrow 2D$$

...which of the following is the rate law for the reaction based on the following data?

Exp # [A] [B] [C] Rate of disappearance (M/s)
1 0.1 0.1 0.1 x
2 0.2 0.2 0.1 8x
3 0.2 0.1 0.1 4x
4 0.2 0.1 0.2 32x
A

$\text{rate} = k[A]^2[B][C]$

B

$\text{rate} = k [A]^2[B][C]^3$

C

$\text{rate} = k[A]^2[B]^3[C]$

D

$\text{rate} = k[A]^2[B]^2[C]^3$
