For the cell reaction
`4Br^(-) + O_(2)+4H^(+) rarr Br_(2)+2H_(2)O`
`E_("cell")^(@)=0.16 V`, the value of log `K_(c)` is :

A

108

B

10.8

C

5.4

D

1080

Text Solution

Verified by Experts

The correct Answer is:
B
`log K_(c)= ( n E_("cell")^(@))/(0.059) ( "at" 25^(@)C)`
`= (4xx0.16)/(0.059)= 10.8`
