Cosoder the reactopm: `(T = 298 K)`
`Cl_2 (g) + 2 BR^(-) (aq) rarr 2 Cl^(-) (aq) + Br_2 (aq.)`
The emf of he cell, when `[Cl^(-) = (Br_2] = [Br^(-) ] = 0.01M and Cl_2 ` gas is at `1` atm pressure, will be :
(`E^@` for the above reaction is `= 29` volt ).

A

` 0. 54 `volt

B

` 0. 35` volt

C

` 0. 24` volt

D

` -0 .29` volt

Text Solution

Verified by Experts

The correct Answer is:
B
` E_(cell) =0 . 29 - (0.9059)/2 log. ( 0.1 xx (0.01)^@)/((0.01)^2xx 1)`
or `E_(cell) = 0.35` volt.
