Explanation:
The given reaction at cathode will be as follows.
At cathode:
,
= -0.761 V
At anode:
,
= 0.761
Therefore, net reaction equation will be as follows.
![Zn^{2+} + Zn \rightarrow Zn + Zn^{2+}](https://tex.z-dn.net/?f=Zn%5E%7B2%2B%7D%20%2B%20Zn%20%5Crightarrow%20Zn%20%2B%20Zn%5E%7B2%2B%7D)
Initial: 0.129 - - 0.427
Change: -0.047 - - -0.047
Equilibrium: (0.129 - 0.047) (0.427 - 0.047)
= 0.082 = 0.38
As
for the given reaction is zero.
Hence, equation for calculating new cell potential will be as follows.
E_{cell} = ![E^{o}_{cell} - \frac{RT}{nF} ln \frac{[Zn^{2+}]_{products}}{[Zn^{2+}]_{reactants}}](https://tex.z-dn.net/?f=E%5E%7Bo%7D_%7Bcell%7D%20-%20%5Cfrac%7BRT%7D%7BnF%7D%20ln%20%5Cfrac%7B%5BZn%5E%7B2%2B%7D%5D_%7Bproducts%7D%7D%7B%5BZn%5E%7B2%2B%7D%5D_%7Breactants%7D%7D)
= ![0 - \frac{8.314 atm L/mol K \times 291 K}{2 \times 96500} ln \frac{0.38}{0.082}](https://tex.z-dn.net/?f=0%20-%20%5Cfrac%7B8.314%20atm%20L%2Fmol%20K%20%5Ctimes%20291%20K%7D%7B2%20%5Ctimes%2096500%7D%20ln%20%5Cfrac%7B0.38%7D%7B0.082%7D)
= 0.019
Thus, we can conclude that the cell potential of the given cell is 0.019.
Chloropicrin is obtained by the reaction of nitric acid on chloroform.
chegg 2. What pattern did you observe measuring cell voltages with a silver electrode versus with a platinum/H2 electrode There is a difference of -0.786 V in silver
<h3>What is cell voltages ?</h3>
The difference in electric potential between two points, also known as voltage, electric potential difference, electric pressure, or electric tension, is what determines how much labor is required to move a test charge between the two sites in a static electric field. Volt is the name of the derived unit for voltage (potential difference) in the International System of Units. Joules per coulomb, or 1 volt equals 1 joule (of work) for 1 coulomb, is how work per unit charge is stated in SI units (of charge). The quantum Hall and Josephson effect was first employed in the 1990s, and most recently (in 2019), fundamental physical constants have been added for the definition of all SI units and derived units. Power and current were used in the previous SI definition for volt.
