equation for Q

Postby Savannah Mance 4G » Wed Mar 04, 2020 12:01 pm

Is the equation for Q from the cell diagram always going to be the anode over the electrode? Like for 6N.1 in the textbook with the rxn Mn(s)+Ti^2+---->Mn^2+ +Ti(s)? Or is it just like you'd normally do Q with products over reactants?

Yes for Q the anode is always over the cathode. It is very confusing because you would think it would be cathode over anode but in the case of the nernst equation it is the opposite

It will always be the anode over the cathode since the equation for Q is products over reactants. The products of the equation will be the anode concentration and the cathode concentration will be the reactants.

And this is also the case since you do not consider solids for equilibrium?
