If $k,$

$()0,$ and $C_{A0}$ are constants equal, respectively, to $2\mathrm{.}0,4\mathrm{.}6,$ and $20.$ The parameter $x$ varies from an initial value $0$ to a final value of $0\mathrm{.}92,$ what is the value of $V$ given the following equations and assuming that the integral of $dV$ equals $V$ :

$\frac{d{C}_A}{dV}=\frac{r_A}{?}$

$()0$

A change of variables from $d{C}_A$ to $dx$ is helpful.

Express your answer to one decimal place.
