Table J & Spontaneous rxns

• Spontaneous Rxns


  Occurs w/o adding energy to system
• If "single "element intre active than "combined "element

  Rxn is spontaneous
• If single metal is higher than combined metal

  Spontaneous rxn
• Zn is above Pb on Table J

  Zn is strong
• Non-Spontaneous rxn


  Rxn will not occur unless energy is added to system
• Non-spontaneous reaction


  • Zn+AlCl → No rxn
• If combined metal is higher than single metal


  Not spontaneous
• Al is above zn on Table 3

  Al is stronger, lose e- easily
• Activity of metals(On left side of Table J)


  • Most active metals ->Top of Table J (Easily oxidized)
  • Least active metals -> Bottom of Table J (Not easily oxidized)
• Activity of non-metals (On the right side of Table J)


  • Most active non-metals, Top of Table J (Easily reduces)
  • Least active nonmetals, Bottom of Table J (Not easily reduced)
• If the single element is a non-metal in the answer choices, look on the non metal side on Table J
