How does concentration and stirring affect decomposition potential?

Click For Summary
SUMMARY

The discussion focuses on how the concentration of sulfuric acid electrolyte and stirring influence the decomposition potential in electrochemical reactions. It is established that increased concentration of sulfuric acid reduces concentration polarization, thereby affecting the decomposition potential. The relevant equation for this analysis is ED = Ecathode - Eanode + ɳ, where ɳ represents the overpotential. The conversation emphasizes the need to clarify the specific decomposition reaction being studied to fully understand the effects of these variables.

PREREQUISITES
  • Understanding of electrochemical reactions and decomposition potential
  • Familiarity with sulfuric acid as an electrolyte
  • Knowledge of concentration polarization in electrochemistry
  • Basic grasp of the equation ED = Ecathode - Eanode + ɳ
NEXT STEPS
  • Research the effects of electrolyte concentration on electrochemical reactions
  • Study the role of stirring in enhancing mass transport in electrochemistry
  • Learn about the specific decomposition reactions involving sulfuric acid
  • Explore the concept of overpotential and its implications in electrochemical systems
USEFUL FOR

Chemical engineers, electrochemists, and students studying electrochemical processes will benefit from this discussion, particularly those interested in the effects of electrolyte concentration and stirring on decomposition potential.

Homework Statement


Decomposition potential can be affected by the concentration of sulphuric acid electrolyte and whether there is stirring. Explain how they affects.

Homework Equations


ED = Ecathode - Eanode + ɳ
where ɳ is the overpotential

The Attempt at a Solution


I'm thinking that the decomposition potential here is referred to the experimental decomposition potential since overpotential is involved.
Also, I think that the increase in concentration of the acid reduces the concentration polarisation same goes for stirring but I'm not sure whether I'm correct and I need help in linking back to decomposition potential

Decomposition of WHAT? Can you write a reaction for the decomposition? Where in that reaction might sulfuric acid (or some species derived from sulfuric acid) appear, or have an effect?
