23.5 Predictions from electrode potentials

• You can predict the feasibility of redox reactions from standard electrode potentials

  • the more positive electrode potential will act as the oxidising agent and the more negative electrode potential will act as the reducing agent
• Standard electrode potentials can be predicted but may not take place in practice

  • reaction may have a large activation energy
  • concentration may not be 1 mol dm-3
  • may not be standard conditions
