Ah, that should help! Maybe an equation would help structure and direct your answer. Considering the potential values and OIL RIG, you should be able to formulate one (don't forget to cancel species once your electrons are balanced). Also, the question mentions a gas. How might this help you in answering? Do you need a labelled diagram? How many marks is the question worth? <-- These are the sorts of qus you should be asking yourself as you go along.

Manganate equilibria are a personal fave with the colour changes (transition metal chem links in too!), and I think exam boards usually quite like them as well... Briggs-Rauscher is fun to watch if you fancy colour changes too

Believe you’ll be using system 1 and 4 the backward rule shows that Reaction 1 happens in reverse ( Due to the more negative electrode potential) so you’d be producing CO2 gas for the observation. Not sure what you need to state about the equilibrium.
