I keep getting “Nernst equation” questions wrong in Electrochemistry. What's the trap?
using standard potentials when concentrations aren't 1 M.
The usual trap: using standard potentials when concentrations aren't 1 M. How to avoid it: ΔG = −nFE links free energy to cell voltage. Go back to the definition — adjusts electrode potential for non-standard concentrations.
Key point
Nernst equation
Common mistake
using standard potentials when concentrations aren't 1 M.
Memory tip
ΔG = −nFE links free energy to cell voltage.
