Charge/discharge characteristics chemical properties

Activation energy must be supplied before these processes and the magnitudes depend on the properties of the reactants, products and intermediates for most physical and chemical reactions. If any one of the reactions listed is slower than the activation, thermal and electrical output will control the cell s current voltage characteristics. The slow step may occur before or after the electron transfer step and may not involve charged particles. If the products or reactants of the non-electrical reaction participate in electron transfer, then potential will affect the kinetics by its effect on reactant activity. This potential dependent for the non-current producing reactions is due to chemisorption prior to electron transfer and a surface reaction following the ion discharge.
