Consider the reaction: `(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-(0.059)/(2)log((0.01xx(0.01)^(2))/((0.01)^(2)xx1))` or `E_(cell)=0.35"volt"`
