# Is the rate of electrolysis the same throughout as long as voltage is same

In an electrolytic cell, where the electrolysis of dilute sulfuric acid is taking place, would the rate of electrolysis be constant always, even at the beginning?

By rate of electrolysis, I mean the rate of gas production or the rate of charge delivery. And would this rate be established as soon as I turn on the voltage, or does it slowly increase to a constant level?

• No, no and no. // The rate depends on area of electrodes. So for a given voltage, bigger electrodes have a higher reaction rate. // The instantaneous rate is high because there is no double barrier. // Immediately after the cell starts, a double layer forms and the reaction rate lowers and becomes controlled by diffusion to the electrodes from the bulk solution. – MaxW Jul 14 '19 at 15:32
