The overall reaction 2co3+(aq) + 2cl–(aq) → 2co2+(aq) + cl2(g) has the standard cell voltage e°cell = 0.46 v. given e° = 1.36 v for the reaction cl2(g) + 2e– → 2cl–(aq), calculate the standard reduction potential for the following the half reaction at 25°c: co3+ + e– → co2+

The standard reduction potential for reduction half reaction is 1.82 V

Explanation:

The given chemical reaction follows:

Oxidation half reaction:  

Reduction half reaction:  

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 for reduction half reaction is 1.82 V

it is b that is the answer.
