The question is incomplete, here is the complete question:
What is the calculated value of the cell potential at 298 K for an electrochemical cell with the following reaction, when the H₂ pressure is 6.56 x 10⁻² atm, the H⁺ concentration is 1.39 M, and the Sn²⁺ concentration is 9.35 x 10⁻⁴ M?
<u>Answer:</u> The cell potential of the given electrochemical cell is 0.273 V
<u>Explanation:</u>
For the given chemical equation:
The half cell reactions for the given equation follows:
<u>Oxidation half reaction:</u>
<u>Reduction half reaction:</u>
Oxidation reaction occurs at anode and reduction reaction occurs at cathode.
To calculate the of the reaction, we use the equation:
Putting values in above equation, we get:
To calculate the EMF of the cell, we use the Nernst equation, which is:
where,
= electrode potential of the cell = ?
= standard electrode potential of the cell = +0.14 V
n = number of electrons exchanged = 2
Putting values in above equation, we get:
Hence, the cell potential of the given electrochemical cell is 0.273 V
