Question
The temperature coefficient, of the emf i.e. 
= - 0.00065 volt. deg-1 for the cell Cd | CdCl2 (1M) | AgCl (s) | Ag at 25oC. Calculate the entropy changes ᐃS298K for the cell reaction, Cd + 2AgCl → Cd++ + 2Cl- + 2Ag

A.- 105.5 JK-1
B.- 150.2 JK-1
C.- 75.7 JK-1
D.- 125.5 JK-1
Solution
= - 0.00065 Vol deg-1ᐃS298 = n.F.
= 2 × 96500 × (-0.00065) = - 125.5 J/K.Create a free account to view solution
