please solve:In the PFR reactor, a liquid phase dimerization process was run $2A$ Products. The composition

of the monomer at the entrance is $1$mol$/$L$.$ The reversibility of the process is $90\%.$ What will be

the increase in production with components in a well$-$stirred reactor column whose volume is

double that of the existing PFR reactor and in what order should the well$-$stirred reactor be

installed. It should be taken into account that the final conversion is equal to $90\%.$
