• concentration of reactants decrease
  • frequency of successful collisions decrease
    • between cathode and electrolyte, anode and electrolyte
    • rate of reaction decreases
  • if a singular reaction occurs per second
    • current = Q/t x transfer of electrons (rate) decreases
    • if rate of reaction goes down, the transfer of electrons is slowing down.
  • current decreases
    • therefore emf decreases
  • what is way of fixing this?
    • fuel cells: lit-ion battery
      • no longer in course because research is ongoing
      • nickel cad
  • why sulfuric acid and other polyprotic acid not allowed
    • we are only allowed to work with H+ ions in a 1mol/L
    • we are operating SRP => H+ > 1.0 mol/L
    • if we change the concentration, then the order of rankings will change
    • citric acid and organic acids are weak acids
      • the concentration doesnt have 1mol/L of hydrogen either, if you put 1mol/L in.
  • higher elevation = lower pressure lower temperature
    • rate of reaction decreases
    • voltage decreases
  • electrolyte concentration and voltage developed.
    • if concentration increases, rate of reaction increases and voltage increase.
    • the time it last does not depend concentration, it depends on moles (?) which depends on the size of the battery.
  • concentration => ror => v
  • moles => duration
  • internal resistance
    • corrosion of e- comp
    • decrease ion mobility = load/acid battery (?)
  • voltage/time graph
