Need both parts pleaseee!! I think for part B can only use the graph to find the volume.

8. The reaction described by the data in the figure below is to be carried out in a CSTR. Species A enters the reactor at a molar flow rate of FA0=0.4smol a) Calculate the volume necessary to achieve 80% conversion in a CSTR using the equatio V=(rA)exitFA0X b) Calculate the volume necessary to achieve 80% conversion in a CSTR only the graph
