Calculate e.m.f a

Answer :

For given reaction we identify the oxidation and reduction half-cell reactions





For the cell as Ag2+ has positive reduction it tends to udergo reduction. For the given cell representation,




The emf of a cell is given by,






The emf of cell is 1.0796 V


The Gibbs free energy is given by,




The Gibbs free energy is ΔG = 208.4 kJ


OR


(a)


Given:


k = 1.06×10-2 cm-1


C = 0.1 M


To find: molar conductivity and degree of dissociation


We know that,




Molar conductivity is 106


Molar conductivity


Degree of dissociation



Degree of dissociation = 0.837


(b)
