Determine overall reaction is spontaneous

Reference no: EM13714523

Problem- Given the following two half-reactions, determine which overall reaction is spontaneous and calculate its standard cell potential.

Cd2+(aq) + 2 e- --> Cd(s) E° = -1.21 V

Sn2+(aq) + 2 e- --> Sn(s) E° = -0.14 V

a) Cd2+(aq) + Sn(s) --> Cd(s) + Sn2+(aq) = +1.07 V

b) Cd2+(aq) + Sn(s) --> Cd(s) + Sn2+(aq) = -1.35 V

c) Cd(s) + Sn2+(aq) --> Cd2+(aq) + Sn(s) = +1.07 V

d) Cd(s) + Sn2+(aq) --> Cd2+(aq) + Sn(s) = -1.07 V

e) Cd(s) + Sn2+(aq) --> Cd2+(aq) + Sn(s) = +1.35 V

Please demonstrate the entire work. I am thanking you in advance
