Please tell me what was pht into Polymath and$/$or excel! The following reaction is to be carried out in the liquid phase in semi$-$batch mode:

$()-$

There is a feed rate of $0\mathrm{.}2\frac{L}{s}$ of NaOH solution $(0\mathrm{.}2M)$ added to $1200L$ of ethyl acetate solution $(0\mathrm{.}25M)$ at a temperature of $35C.$ The rate constant $k=5\mathrm{.}2{10}^{-5}\frac{m^3}{m}o\frac{l}{sec}$ at $20C$ with $E=42,810\frac{J}{m}ol.$ Plot reaction rate, concentration of reactants and products, and number of moles of sodium acetate as a function of time. Another problem you'll want to set up in a numerical solver. You'll also need to define your equations in terms of molar flow rates instead of conversion $($which won't work for a semibatch reactor$)$
