The following irreversible elementary liquid phase reaction is taking place in a $0\mathrm{.}01$ m$3$ PFR which is mounted with a heat exchanger. $2$A$----->$ B The feed at $400$ contains only A and the concentration of A in the feed is $1$ kmol$/$m$3$ and the molar flow rate of it is $300$ mol$/$min$.$ The heat capacities of A and B are $122$ J$/$mole$.$K and $244$ J$/$mole$.$K$,$ respectively. The $$Ua$$ value for the heat exchanger is $5000$ J$/$s$.$dm$3/$K and the heat exchanger fluid has a temperature of $425.$ The heat of reaction $($Hrxn$)$ and the rate constant $($k$)$ of the reaction are a function of temperature according to the following expressions: $$Hrxn $=-23100012($T$-25)$ J$/$mole where T is in $$ k $=1\mathrm{.}48$ x $108$ exp $(-19124/$T$)$ dm$3/$mole$.$s where T is in K Determine the conversion of A that can be achieved in this reactor. please use polymath and what is the conversion of A $=?$ please solve clearly and find conversion of A$.$ pleasee find XA$.$ not run my polymath. what is the conversion of A$.$
