350\,\text{K}

, the reaction

X + 2Y \to \text{products}

follows the rate law

rate = k[X][Y]^2

. For a trial in which

[X] = 0.0350\,\text{M}

and

[Y] = 0.150\,\text{M}

, the initial rate is

1.65 \times 10^{-4}\,\text{M}\cdot\text{s}^{-1}

. Determine

k

, expressing your answer in scientific notation with appropriate units.
