QUESTION H$1$

The decomposition of gasedus reactant $A$ in a constant$-$volume batch reactor at $100C$ yelded the followine data:

$\backslash$table$[[$Time $t$ in sec$,$Pressure $p_{}$ in atm$],[0,1\mathrm{.}00],[20,0\mathrm{.}80],[40,0\mathrm{.}68],[60,0\mathrm{.}56],[80,0\mathrm{.}45],[100,0\mathrm{.}37],[140,0\mathrm{.}25],[200,0\mathrm{.}14],[260,0\mathrm{.}08],[330,0\mathrm{.}04],[440,0\mathrm{.}02]]$

The stoichiometry of the reaction is $2AR+S.$

$($a$)$ What size of plug fow reactor $($in liters$)$ operating at $100C$ and $1$ atm can treat $120$ moles of A per liter in a feed conlaining $20$s inerts to obtain $95\%$ corversion of $A?$

$($b$)$ What size of mised flow reactor $($in liters$)$ operating at $100C$ and $1$ atm can trest $120$ moles of A per liter in a feed containing $20\%$ inerts to obtain $95\%$ conversion of $A?$
