Speed at which molecules break down using electricity

Click For Summary

Discussion Overview

The discussion revolves around the factors influencing the breakdown of molecules using electricity, particularly in the context of electrolysis. Participants explore the roles of voltage and current, as well as the chemical properties of different molecules.

Discussion Character

  • Exploratory
  • Technical explanation
  • Conceptual clarification

Main Points Raised

  • One participant questions whether voltage, current, or another factor determines the rate of molecular breakdown when using electricity.
  • Another participant suggests that the applied voltage must be sufficient to separate the molecule, while the current influences the rate at which the substance reaches the electrodes.
  • A different participant emphasizes that the specific molecule in question significantly affects the required electric field strength, noting that some molecules may need only a few volts per meter, while others could require megavolts per meter.
  • This participant also mentions the example of oxygen molecules and their bonding to hemoglobin, highlighting that even slight changes in oxygen concentration can affect binding and release, indicating the need for low electrical potentials in such cases.

Areas of Agreement / Disagreement

Participants express differing views on the factors that influence the breakdown of molecules, with no consensus reached on a singular determining factor.

Contextual Notes

The discussion does not resolve the complexities involved in the electrolysis process, including the specific chemical properties of various molecules and the assumptions regarding electric field strengths.

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?

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
