The potential of the Daniell cell, Zn 
Cu was reported by Buckbee, Surdzial and Metz as Eo = 1.1028 - 0.641 × 10-3 T + 0.72 × 10-5 T2, where T is the temperature in degree celsius. Calculate ᐃSo for the cell reaction at 25oC :
Cu was reported by Buckbee, Surdzial and Metz as Eo = 1.1028 - 0.641 × 10-3 T + 0.72 × 10-5 T2, where T is the temperature in degree celsius. Calculate ᐃSo for the cell reaction at 25oC :Options
A.- 45.32 EU
B.- 34.52 EU
C.- 25.43 EU
D.- 54.23 EU
Solution
Eo = 1.1028 - 0.641 × 10-3 T + 0.72 × 10-5 T2
= - 0.641 × 10-3 + 2 × 0.72 × 10-5 T
= (-0.641 + 0.36) × 10-3 = - 0.281 × 10-3
ᐃSo = nF
= 2 × 96500 × (-281 × 10-3) = - 54.23 EU
= - 0.641 × 10-3 + 2 × 0.72 × 10-5 T= (-0.641 + 0.36) × 10-3 = - 0.281 × 10-3
ᐃSo = nF
= 2 × 96500 × (-281 × 10-3) = - 54.23 EUCreate a free account to view solution
