Question

This equation depends on a “charge transfer coefficient” that quantifies the asymmetry of the potential barrier. For 10 points each:
[10h] Name this doubly eponymous equation in electrochemical kinetics. This equation states that the current at an electrode is the sum of two contributions, one exponentially increasing in the voltage and one decaying.
ANSWER: Butler–Volmer equation
[10e] The electrode current cannot grow indefinitely with increasing voltage; it is eventually limited by the rate at which this process brings fresh reactants to the surface. This process transports species from high to low concentration.
ANSWER: diffusion
[10m] The rates are exponential in this quantity, symbolized eta. This quantity measures the difference between a reaction’s equilibrium potential and the potential of the electrode where it is occurring.
ANSWER: overpotential
