Questions and Answers

In electrochemistry, where do the reactions involving electrons moving take place?

  • In the surrounding atmosphere
  • Between electrodes separated by an ionically conducting and electronically insulating electrolyte (correct)
  • Within the electrodes
  • Within the ionic species in a solution

    • What distinguishes an electrochemical reaction from a conventional chemical reaction?

  • Electrons are transferred via an electronically-conducting circuit (correct)
  • Generation of light as a byproduct
  • Higher energy release
  • Involvement of only solid-state materials

    • When is a chemical reaction called an electrochemical reaction?

  • When it involves high temperature
  • When it involves only gaseous reactants
