Question

In the button cells widely used in watches and other devices the following reaction takes place: Zn(s) + Ag2O(s) + H2O(l) → Zn2+(aq) + 2Ag(s) + 2OH -(aq) Eø = 1.104 V Determine log Kc and equilibrium constant for the reaction.

Answer 1

Answer:

G= - nFE(cell) and G= - 2.303 RT log K

Explanation:

so,

by comparing these,

nFE = 2.303 RT logK

F= 98500
