Speed at which molecules break down using electricity

[black phantom]

When breaking down a molecule using electricity, what determines how much of the substance is broken down per second. Is it the voltage, current, or something else I'm not thinking of?

You mean like with electrolysis?
The applied voltage needs to be big enough to pull the molecule apart but the current controls the rate of production (it's the rate the substance arrives at the electrodes).

It all very much depends upon what molecule you're discussing; this question relates very closely to the Chemistry involved. Some will require an electric field of only a few volts per metre whilst some will require Megavolts per metre.
If you consider the way Oxygen molecules bond to Haemoglobin in the red cells, only a very slight difference in concentration of Oxygen will cause the Oxygen to be held or released. the electrical potentials in each case must be extremely low.

I need some suggestion for preparing GATE 2013 Electrical Engg where as I have completed my BE In Electronics and Telecomm.How to prepare for Gate and which reference is to be used.
Thanking you

The speed at which molecules break down using electricity is determined by multiple factors, including the voltage, current, and the properties of the molecule itself. The voltage and current play a crucial role in determining the rate of electron transfer, which is necessary for the breakdown of molecules. However, the properties of the molecule, such as its size, shape, and chemical bonds, also play a significant role in the breakdown process.

Additionally, the type of electricity being used can also affect the breakdown rate. For example, direct current (DC) and alternating current (AC) may have different effects on the breakdown of molecules. The environment in which the breakdown is taking place can also play a role, as temperature and pressure can influence the rate of reaction.

In summary, the speed at which molecules break down using electricity is a complex process that is influenced by multiple factors, including voltage, current, molecule properties, type of electricity, and environmental conditions. Further research and experimentation are needed to fully understand and control this process for various applications in fields such as chemistry, materials science, and energy production.
