In the activity, click on the E?cell and Keqquantities to observe how they are related. Use this relation tocalculate Keq for the following redox reaction that occursin an electrochemical cell having two electrodes: a cathode and ananode. The two half-reactions that occur in the cell are

Cu2+(aq)+2e??Cu(s) and Fe(s)?Fe2+(aq)+2e?

The net reaction is:

Cu2+(aq)+Fe(s)?Cu(s)+Fe2+(aq)

Use the given standard reduction potentials in your calculationas appropriate.

Express your answer numerically to three significantfigures.

Given the two half-cells: [reduction potentials from CRC 71st ed, p 8-17]

Fe2+ + 2e- --> Fe Eo = -0.447 V

Cu2+ + 2e- --> Cu Eo = + 0.342 V

a.) Given the two possible reactions:

1.) Fe2+ + Cu --> Fe + Cu2+ or

2.) Cu2+ + Fe --> Cu + Fe2+

which would be the spontaneous reaction (enter 1 or 2).

b.) If the two half-cells were joined, what is the Eo for the reaction which will occur spontaneously?

c.) What would be the cell potential for a copper-iron electrochemical cell in which [Cu2+] = 0.100 M and [Fe2+] = 0.100 M?

d.) What would be the cell potential for a copper-iron electrochemical cell in which [Cu2+] = 0.002 M and [Fe2+] = 0.198 M?

2. n the copper-iron electrochemical cell above, which metal electrode (Fe or Cu) is the anode?

A. Fe

B. neither

C. Cu

D. both

3. In which direction will the electrons flow during this spontaneous reaction?

A. From Fe to Cu

B. no electron flow will occur

C. From Cu to Fe

Given the two half-cells:

Pb2+ + 2 e- --> Pb Eo = -0.1262 V

Sn2+ + 2 e- --> Sn Eo = -0.1375 V

As an electrochemical cell discharges, the concentrations of the various species change. If you started with 100.0 mL of 0.1000 M Pb2+ in the lead half cell and 100.0 mL of 0.1000 M Sn2+ in the tin half cell, at what concentration of each would the cell have a cell potential of zero?

[Sn2+] = ?M = [Pb2+] = ?M

BRICS is a new Organization investing in Marble Production in Ethiopia. The CEO and owner of BRICS 
Company is Mrs. Hariet Obang. Five years ago, Mrs. Hariet recruited 500 employees based on the 
strategic plan of the Company and the number of employees has now declined to 300. The cause for 
employee turnover is said to be lack clear compensation schemes as compared to other industries. This 
has caused a continuous decrease in performance and also marble production particularly in the last six 
months.
The CEO, Mrs. Hariet decided to undertake some reform to enhance performance and productivity 
basically by undertaking some changes in the areas of Human Resource. The CEO’s assumption is that 
she has few employees while she has failed to recruit new employees because of scarcity in the market. 
She is also intending to have included Human Resources into Organizational Plan and align with 
Organizational Strategy. 
However, unless she takes some measure in the coming few weeks she is going to be in trouble in terms 
of productivity and performance.

Assume that you are an HR manager in an Organization in Ethiopia. Assume also that there are excess 
employees in your Organization while the market is also good in accessing better employees. The CEO 
of the Organization in which you are working asked the middle manager to come up with an 
assessment that can enable him adjust the discrepancy created. 
If the HR middle Manager (the one assignment is given) in your Organization comes to you for pieces of 
advices as to how to go about it, what can you say to this manager? Tell him detailed information 
considering that you have prepared the said assessment report.
