Finding the concentration of cathodes/ anodes
For solving for the concentration of cathodes or anodes, are you able to use the Nernst equation? I know that there is the ln of Q, which is product over reactant, so how would you know if the anode or cathode is the reactant or product in the equation?

Yes, you can use the Nernst equation, provided all the other info is given. If it's a concentration cell, the cathode is the half-cell with the higher concentration, so it'll be the reactant. If it's a normal galvanic cell, you would identify the reactant and product from the overall equation of the reaction.
I hope this helped!

For the concentration cell, is the reactant always the half rxn with a high concentration and why?
