The mass of a substance altered at an electrode during electrolysis is directly proportional to the quantity of electricity transferred at that electrode. ... more

In chemical kinetics, the pre-exponential factor or A factor is the pre-exponential constant in the Arrhenius equation. Here named as Arrhenius number.
