The R component dissolved in the liquid phase turns into the product at the rates specified in the table below.

CR$($mol$/$l$)0\mathrm{.}51\mathrm{.}02\mathrm{.}03\mathrm{.}04\mathrm{.}56$

$-$rR$($mol$/$l min $)0\mathrm{.}030\mathrm{.}050\mathrm{.}1250\mathrm{.}50\mathrm{.}50\mathrm{.}25$

How many minutes should the reaction time take in the batch reactor for the R component, whose initial concentration is $5$mol$/$L$,$ to drop to $1$mol$/$L$?$
