Answer:
The anode made of the impure copper
The cathode made of pure copper
The electrolyte of copper (II) sulfate CuSO₄ solution
The silver impurities at the anode due to their high tendency of accepting electrons and being a stronger reducing agent than either copper or zinc will remain relatively in place and relatively stable and will not actively take part in the oxidation reaction taking place at the anode
The zinc impurities will be the first element of the three metals to give up electrons and go into the solution as zinc ions due to their high tendency to loan out two electrons and become oxidized into Zn²⁺ ions

Explanation:
As it is given that mixture (contains 9 mol % A and 91% B) and it is flowing at a rate of 800 kg/h.
Hence, calculate the molecular weight of the mixture as follows.
Weight =
= 27.8336 g/mol
And, molar flow rate of air and mixture is calculated as follows.
= 28.74 kmol/hr
Now, applying component balance as follows.
= 43.11 kmol/hr
= 43.11 - 28.74
= 14.37 kmol/hr
So, mass flow rate of pure (B), is =
= 416.73 kg/hr
According to the product stream, 6 mol% A and 94 mol% B is there.
Molecular weight of product stream =
=
= 28.22 g/mol
Mass of product stream = 1216.67 kg/hr
Hence, mole of into the product stream is as follows.
=
= 272.31 kg/hr
Therefore, calculate the mass % of into the stream as follows.
= 22.38%
Thus, we can conclude that the required flow rate of B is 272.31 kg/hr and the percent by mass of in the product gas is 22.38%.
