Consider the following balanced chemical equation.
$3O_2 + 2CH_3OH \rightarrow 2CO_2 + 4H_2O$
How is the rate of change of $H_2O$, $\frac{\Delta [H_2O]}{\Delta t}$, related to the rate of change of $O_2$?
$-\frac{1}{3} (\frac{\Delta [O_2]}{\Delta t})$
$\frac{1}{3} (\frac{\Delta [O_2]}{\Delta t})$
$-\frac{4}{3} (\frac{\Delta [O_2]}{\Delta t})$
$\frac{4}{3} (\frac{\Delta [O_2]}{\Delta t})$
$\frac{3}{4} (\frac{\Delta [O_2]}{\Delta t})$
$-\frac{3}{4} (\frac{\Delta [O_2]}{\Delta t})$
