A 100 kg/h mixture containing equal parts by mass of benzene and toluene is distilled. The flow rate of the overhead product stream is 48.8 kg/h. The bottom stream contains 7 wt% benzene.       a-Draw and label a flowchart of the process.       b-Calculate the number degree of freedom (NDF) and the mass fraction of benzene in the overhead product stream

For the cell: pt / H₂ (latm) / NaOH cm) / HgO (s) / Hg EHg / Hg²+ Егадк = 0.924V 2+ + 0.854 V calculate standard electromotive force E298 K write the electrods reactions and the cell the cell reaction. So calculate the electromotive force at 308 K when the change in inthalpy (AH) = and, what happen to electromotive force when added few amount of nitric acid to equivalent to the base NaOH partially? 35 Kcal Cell reaction - and

A stream containing propionic acid and water at 70:30 mass ratio is fed to a mixer at 3.181 kg/s with pure cyclohexane as solvent. What should be the flow rate of the solvent in order to attain 30:70 mass ratio of solute and solvent in the extract (solvent-rich) stream? Prepare graphical and computational solution.
