(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.

Question

Chapter 19, Problem 19.39CP

Interpretation Introduction

(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.

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.

2. Please consider the two all 'cis' isomers of trimethylcyclohexane drawn below. Draw the two chair conformers of each stereoisomer below (1 and 2) and calculate their torsional interaction energies in order to identify the lower energy conformer for each stereoisomer. Based on your calculations, state which of the two stereoisomers 1 and 2 is less stable and which is more stable. [1,3-diaxial CH3 CH3 = 3.7kcal/mol; 1,3-diaxial CH3 H = 0.88kcal/mol; cis-1,2 (axial:equatorial) CH3 CH3 = 0.88kcal/mol; trans-1,2-diequatorial CH3 CH3 = 0.88kcal/mol) all-cis-1,2,3- 1 all-cis-1,2,4- 2
