(b) In an existing process, we have a single MFR reactor converting 67% of A through a first order reaction. We think of adding a second identical reactor in series. (i) Using Figure 1 overleaf, for the same treatment rate as that used with the single reactor, calculate the new conversion of A after addition of the second reactor. [5 MARKS] (ii) Using Figure 1, keeping the conversion at 67%, find by how much the treatment rate can be increased. [5 MARKS] (iii) Using hand calculations, verify the treatment rate found in (ii).
