Answer: The most spontaneous reaction will be [tex]A+B\rightarrow C;E^o_{cell}=+1.22V[/tex]
Explanation:
For the reaction to be spontaneous, the Gibbs free energy of the reaction must come out to be negative.
Relationship between standard Gibbs free energy and standard electrode potential follows:
[tex]\Delta G^o=-nFE^o_{cell}[/tex]
The reaction having highest positive [tex]E^o_{cell}[/tex] will be the most spontaneous.
Hence, the most spontaneous reaction will be [tex]A+B\rightarrow C;E^o_{cell}=+1.22V[/tex]
