Cell Diagram Order (14.11) [ENDORSED]

[Hannah Chew 2A]

Can anyone explain the order of the cell diagram? I thought it was reactant first and product second, but in several problems, I found it to be inconsistent.
Ex) 14.11 b) Cl- is written first but is a product.
14.11 e) Cl- / Hg2Cl2 / Hg is written like this in the book, but Cl- and Hg are both products.

I have a similar question and also on part c why is it written as ||Ce4+,Ce3+| because I thought it was supposed to be written as ||Ce4+|Ce3+

There is a comma because they are both aqueous and | indicates a change in phase. Also, I don't think the order for that matters because they are both mixed in an aqueous solution (someone correct me if I'm wrong on that).

The oxidized form should be before the reduced form if both are the same phase. But can anyone answer my original question?

[Chem_Mod]

For cell diagram, within each half part, electrode and solids are written far away from the salt bridge, followed by liquid, gas and aqueous solution. Within each phase, orders are not strictly defined, but people tend to put in the order of reactant to product.
