Examine the process inFigure P3.2.3. No chemical reaction takes place, andxstands for mole fraction. Perform a degree of freedom analysis using the methodology andsymbols presented in class (L3). Do not write the material balance equations. If temperature andpressure are not given in the schematic, do not include temperature and pressure in the analysis. How many variables are unknown? How many are concentrations? Can this problem be solveduniquely for the unknowns? (5 pts
