<u>Answer:</u> The standard reduction potential of X is -1.20 V
<u>Explanation:</u>
For the given chemical equation:
The half reaction follows:
<u>Oxidation half reaction:</u> ( × 2 )
<u>Reduction half reaction:</u>
Substance getting oxidized always act as anode and the one getting reduced always act as cathode.
To calculate the of the reaction, we use the equation:
We are given:
Putting values in above equation, we get:
Hence, the standard reduction potential of X is -1.20 V
