Title: 2 EMF Cell Question
Post by: killdoug on March 11, 2009, 06:30:47 PM

So im having trouble with these 2 EMF question, and I dont know where to start.

Express the EMF of the cell

Pt/In(s)/In₂(SO₄)₃(aq,m)/Hg₂SO₄/Hg(l)/Pt'

in terms of E⁰,t ,y(gamma), m of In₂SO₄(aq)

and...

Calculate the E₂₉₈ for the cell

Cu_l/Zn/ZnCl₂(0.0100m/Kg)/AgCl(s)/Ag/Pt/Cu_r

given gamma of ZnCl₂ is .708V at this molarity and temperature
