Answer:
the correct answer is E
Explanation:
None of the options is correct, because entropy is the thermodynamic magnitude that indicates the degree of molecular disorder of a system, in exothermic processes energy or heat is released to the medium and energy is taken from the medium in endothermic processes, entropy if it depends of the temperature since the temperature is what sometimes determines if the process is spontaneous or not, and the delta universe in spontaneous processes is not always greater than zero, it is more frequently less than zero with negative values.
Answer:
pH = 2.059
Explanation:
At the Cathode:
The reduction reaction is:

At the anode:
At oxidation reaction is:

The overall equation for the reaction is:

The overall cell potential is:



Using the formula for the Nernst equation:

where;
E = 0.66
(Zn^2+)=0.22 M
Then
![0.66 =0.76- ( \dfrac{0.0591}{2})log \bigg ( \dfrac{[Zn^{2+} ] PH_2}{[H^+]^2} \bigg )](https://tex.z-dn.net/?f=0.66%20%3D0.76-%20%28%20%5Cdfrac%7B0.0591%7D%7B2%7D%29log%20%5Cbigg%20%28%20%5Cdfrac%7B%5BZn%5E%7B2%2B%7D%20%5D%20PH_2%7D%7B%5BH%5E%2B%5D%5E2%7D%20%5Cbigg%20%29)
![0.66 =0.76- 0.02955 * log \bigg ( \dfrac{0.22*0.87}{[H^+]^2} \bigg )](https://tex.z-dn.net/?f=0.66%20%3D0.76-%200.02955%20%2A%20log%20%5Cbigg%20%28%20%5Cdfrac%7B0.22%2A0.87%7D%7B%5BH%5E%2B%5D%5E2%7D%20%5Cbigg%20%29)
3.4 = log ( 0.1914) - 2 log [H⁺]
3.4 = -0.7180 - 2 log [H⁺]
3.4 + 0.7180 = - 2 log [H⁺]
4.118 = - 2 log [H⁺]
pH = log [H⁺] = 4.118/2
pH = 2.059
