18.3 relationships between E, G, and K

Cards (7)

  • Voltage = Joules / Coulomb
  • Coulomb measures the amount of charge
  • 96,485 Coulombs = 1 mole e- = 1 Faraday (F)
  • G=G =nFE -nFE
  • E=E =(RT/nF)lnK (RT/nF)lnK
  • E=E =(0.0257/n)lnK (0.0257/n)lnK
  • spontaneous:
    - G
    K > 1
    + E
    nonspontaneous:
    + G
    K < 1
    - E
