[Given: Freezing point of ethanol is $156.0 K$ Density of ethanol is $0.80\,g\,cm ^{-3}$.
Freezing point depression constant of ethanol is $\left.2.00\,K\,kg\,mol\,m ^{-1}\right]$
$A \to {\text{Product ;}}\,\, - \frac{{d[A]}}{{dt}} = {k_1}{[A]^o}$
$B \to {\text{Product ;}}\,\, - \frac{{d[B]}}{{dt}} = {k_2}{[B]}$
Units of $k_1$ and $k_2$ are expressed in terms of molarity $(M)$ and time $(sec^{-1})$ as
