Use cell potential to calculate an equilibrium constant.
Calculate the cell potential and the equilibrium constant for
the following reaction at 298 K:
Cu2+(aq) +
Hg(l) =
Cu(s) +
Hg2+(aq)
Hint: Carry at least 5 significant figures during intermediate
calculations to avoid round off error when taking the
antilogarithm.

Use proper spelling,
grammar and sentence structure. A suggestion is given about the
number of paragraphs needed but you may write more. You may use
quotes but don’t overuse them as putting the author’s ideas in your
own words is key to the learning process and will help you
remember. If you do use a quote put the page number in brackets
right after the quote.

The United States has experienced an unprecedented number of
individuals protesting the use of force by law enforcement
officers. This was precipitated by the George Floyd case. However,
over the past few years our country has seen a number of incidents
where law enforcement officers were alleged to have used excessive
force in the apprehension of individuals. For example, Ferguson,
Illinois and Baltimore, Maryland have both had incidents where the
use of force by officers resulted in civil unrest. In...

Let a be a positive constant number. Draw the graph of a
catenary y=acosh(x/a). Calculate the arc length s from the point
(0,a) to the point (x,acosh(x/a)), and find the expression of the
curve in terms of the parameter s.
Where n is the number of moles of electrons and F=96,500J/V⋅mol e− is the Faraday constant.
Part A
Cell Potential and Free Energy of a Lithium–Chlorine Cell In thermodynamics, we determine the spontaneity of a reaction by the sign of ΔG. In electrochemistry, spontaneity is determined by the sign of E∘cell. The values of ΔG and E∘cell are related by the following formula: ΔG∘=−nFE∘cell where n is the number of moles of electrons and F=96,500J/V⋅mol e− is the Faraday constant.
Part B
Calculate the free energy ΔG∘ of the reaction.
