Determine the volume of a mixing reactor to process the hydrolysis reaction of acetic anhydride, with a large excess of water, at $25$C$,1$ atm, of $1$st order in anhydride, knowing that it is desired to produce $25$ kg$/$h of acetic acid, the speed is $0\mathrm{.}0583$ min$-1,$ the initial concentration of acetic anhydride is $200$ g$/$L$,$ and the conversion $90\%.$ Data: $($CH$3$CO$)2$O $+$ H$2$O $2$ CH$3$COOH.
