The Edegreecell for the following equation Use these standar
The Edegree_cell for the following equation. Use these standard potentials Pb(s) + F_2(g)rightarrow Pb^2+(aq) + 2F^- (aq)
Solution
let me right th ereduction potential
Pb2+ (aq) + 2e- ---> Pb (s) E0 = -0.126 V
F2 (g) ----> 2F- (aq) + 2e- E0 = 2.87 V
reduction potential with highest value undergo reduction
so act as a cathode F2 is cathode
reduction potential with lowest value undergo oxidation
so act as a catode
Pb act as anode
E0 of cell = E0 of cathode - E0 of anode
E0 cell = 2.87 V - (-0.126 V)
E0 cell = 2.996 V
