Question

For the reaction A + B → P with $	ext{rate} = k[A][B]^2$, rate = $3.6 	imes 10^{-2}$ mol dm⁻³ s⁻¹ when [A] = 0.2 M and [B] = 0.1 M. $k$ equals:

Accepted Answer

A. $18$ mol⁻² dm⁶ s⁻¹

$k = 	ext{rate}/([A][B]^2) = (3.6	imes10^{-2})/(0.2 	imes (0.1)^2) = (3.6	imes10^{-2})/(0.002) = 18$ mol⁻² dm⁶ s⁻¹.

Answer

$3.6$ mol⁻² dm⁶ s⁻¹

Answer

$36$ mol⁻² dm⁶ s⁻¹

Answer

$1.8$ mol⁻² dm⁶ s⁻¹

For the reaction A + B → P with $\text{rate} = k[A][B]^2$, rate = $3.6 \times 10^{-2}$ mol dm⁻³ s⁻¹ when [A] = 0.2 M and [B] = 0.1 M. $k$ equals:
