(a) Interpretation: Whether the cell is a galvanic cell or an electrolytic cell should be determined. Concept introduction: The electrolytic cell is an electrochemical cell which an electric current is used to drive a non-spontaneous reaction. So, electrolytic cell is the reverse of galvanic cell. Electrolytic cell converts electrical energy to chemical energy while galvanic cell converts chemical energy into electric energy. An electrolytic cell has two inert electrodes dipped in an electrolyte. These electrodes are connected to source of electric current.

Concept introduction:
The electrolytic cell is an electrochemical cell which an electric current is used to drive a non-spontaneous reaction. So, electrolytic cell is the reverse of galvanic cell. Electrolytic cell converts electrical energy to chemical energy while galvanic cell converts chemical energy into electric energy. An electrolytic cell has two inert electrodes dipped in an electrolyte. These electrodes are connected to source of electric current.
Interpretation Introduction
(b)
Interpretation:
The anode and cathode should be labeled and the direction of ion flow should be shown.
Concept introduction:
In electrolysis, Anode is where oxidation occurs and indicated by positive sign. Cathode is where the reduction takes place and indicated by a negative sign.
Electrons flow from anode towards the cathode. Anode attracts anions and cathode attracts cations.
Interpretation Introduction
(c)
Interpretation:
The balanced equation for the anode, cathode and overall reaction should be written.
Concept introduction:
When an aqueous solution is electrolyzed, electrolysis products may differ than when the molten salt is electrolyzed. Because water is also electrolyzed.
3) Determine if the pairs are constitutional isomers, enantiomers, diastereomers, or mesocompounds.

In the decomposition reaction in solution B → C, only species C absorbs UV radiation, but neither B nor the solvent absorbs. If we call At the absorbance measured at any time, A0 the absorbance at the beginning of the reaction, and A∞ the absorbance at the end of the reaction, which of the expressions is valid? We assume that Beer's law is fulfilled.
