4. Which of the following reactions would be the most spontanuos at 298k?

a. A+2B--> C Ecell=+.98V

b. A+B--> C Ecell= -.030V

c.A+B---> 3C Ecell=+.15

d. A+B--->C Ecell= +1.22V

e. More information is needed to detwermine.

5. Balance the following redox reaction if it occurs in basic souultion.

H2O2(l)+CIO2--> CIO2-(aq)+O2(g)

6. Use the tabulated half-cell potentails to calculate Delt G for the following redox reaction.

2Al(s)+3Mg2+(aq)-->2Al3+(aq)+3Mg(s)

7. Calculate the cell potential for the following reation that takes place in an electrochemical cell at 25degress C.

Sn(s) I Sn2+(aq, .29M) II Ag+(aq,1.35M) I Ag(s)

Explanation / Answer

4)

G = -n*F*Eo

Greater the positive value of Eo, more negative will the G.

Greater negative G implies greater spontaneity

So, greater Eo value means greater spontaneity.

Most spontaneous one will be d
