The diagram below shows a process to produce a product E from A and B. In addition to the information labeled on the diagram, it is known that the recycle stream to Reactor P (stream 6) has the molar ratio of A to B equal to 1:9. You are asked to find (1) the split ratio of the recycle to purge flow and (2) the overall fractional conversion of A.
