Question $3$:

We are planning to operate a batch reactor to convert A into $R.$ This is a liquid reaction, the stoichiometry is $AR,$ and the rate of reaction is given in the following table. How long must we react each batch for the concentration to drop from $C_{A,0}=1\mathrm{.}3mo\frac{l}{?}$ liter to $C_{A,f}=0\mathrm{.}3mo\frac{l}{?}$ liter?
