Question
The Ecell for a given cell is 1.2346 and 1.2340 V at 300 K and 310 K, respectively. Calculate the change in entropy during the cell reaction if the redox change involves three electrons
Options
A.-17.37 J K-1
B.+17.37 J K-1
C.173.7 J K-1
D.5.79 J K-1
Solution
By ᐃS = 
ᐃH = - nF
and ᐃG = - nEF
ᐃS = - nF
= 3 × 96500 × 
= - 17.37 JK-1
ᐃH = - nF
and ᐃG = - nEF ᐃS = - nF
= 3 × 96500 × = - 17.37 JK-1
