A binary distillation is performed so that a distillate 94% and bottoms 8% in of the more volatile Component A results. The process shown below reflects one operating condition of a feed stream. Rectification, Stripping and the q-line are all provided on the x-y diagram below. Aling with expected stage for the distillation.. Solve a), b) c)

DRAW 2D DIAGRAM OF A SOLUTION TO  MAKE THE MIXING MUCH MORE EFFICIENT A first order irreversible reaction is conducted in an 800 L continuously stirred tank, in liquid solution at 80 ᵒC temperature. The total conversion in the tank is calculated to be 60%. However, this conversion appears low.After a quick check, you realise that something in the mixing is not working correctly and as a result, the tank is not optimally stirred. Following a few tests on residence times, you calculate that approximately 300 L of the tank do not interact appreciably with the input or output streams. You therefore decide to modify the reactor by improving the stirring performance in order to obtain complete mixing in the reactor volume. Describe what considerations allowed you to evaluate the ‘unused’ volume in the tank and defend your proposed solution in a brief technical report to be presented to your manager for approval. The report must include a clear schematic drawing of your selected solution
