The Standard electrode potentials of some electrodes are given below:
`E^@_(Zn^(2+)Zn) = -0.76 V, E^@(Cu^(2+)Cu) =+0.34, E^@_(Ag, Ag) = + 0.80V, E^@_(H, H_2)=0V`
Find the value of `K_e` (equilibrium constant) in the Daniell cell at 298 K

Text Solution

Verified by Experts

At 298 K,for Daniell cell,`E_(cell)^0=0.059/2log K`
`thereforelog K_c=(2xxE_(cell^0)/0.059=(2xx1.1)/0.059=37.29 therefore K_c =antilog (37.29)`
