The temperature coefficient of a cell whose operation is based on the reaction
`Pb(s)+HgCl_2(aq)toPbCl_2(aq)+Hg(l)` is :
`((dE)/(dT))_P=1.5xx10^(-4)VK^(-1)` at 298 K
The change in entropy (in J/k mol) during the operation is :

A

8627

B

57.9

C

28.95

D

14.475

Text Solution

Verified by Experts

The correct Answer is:
C
`DeltaS = n F ((dE)/(dT))_(p) implies 2 xx 96500 xx 1.5 xx 10^-4`
`implies 28.95 J//K` mol
