What is the cell entropy change `(` in `J K ^(-1))` of the following cell `:`
`Pt(s)|underset(p=1atm)(H_(2)(g))|CH_(2)underset(0.1M)(COOH,HCl)|underset(0.1M)(KCl(aq))|Hg_(2)Cl_(2)(s)|Hg`
The `EMF` of the cell is found to be `0.045 V` at `298K` and temperature coefficient if `3.4xxx10^(-4)V K^(-1)`
`(` Given `:K_(a(CH_(3)COOH))=10^(-5)M)`

A

60

B

`65.2`

C

`69.2`

D

`63.5`

Text Solution

Verified by Experts

The correct Answer is:
b
Use `:DeltaS=nF((dE_(ell))/(dT))_(P)=2xx96500xx3.4xx10^(-4)`
`=65.2J K^(-1)`
