From data, 

(a) Derive an equilibrium constant for reaction (24.13), and explain why this reaction (the fixing of photographic film) is expected to go essentially to completion.

(b) Explain why NH3(aq) cannot be used in the fixing of photographic film.

Reaction (24.13)

AgBr(s) + 2S,O3(aq)  [Ag(SO3)2] (aq) + Br(aq) (24.13)

AgBr(s) + 2S,O3(aq) [Ag(SO3)2] (aq) + Br(aq) (24.13)
