Catalytic Converter

• Catalytic Convertor

  1. Present in car exhausts; contains transition metal catalysts of platinum and rhodium
  2. Aids redox reactions to neutralize toxic pollutants formed as a result of incomplete fuel combustion  (a) Carbon monoxide (b) Nitrogen oxides (c) Unburned hydrocarbons
• Reaction equations

  1. 2CO+ O2 → CO2
  2. 2NO + 2CO -> N2 + 2CO $_2$
  3. $C_8H_{18\ +\ }12\ \frac{1}{2}O_2$ --> $8CO_2\ +$$9H_2O$
