1.	An exammple of autocatalysis is
Answer» Oxidation of NO to `NO_(2)` Oxidation of `SO_(2)` to `SO_(3)` Decomposition of `KClO_(3)` to `KCl` and `O_(2)` Oxidation of OXALIC acid by acidified `KMnO_(4)` Solution :`2KMnO_(4)+5H_(2)C_(2)O_(4)+3H_(2)SO_(4)toK_(2)SO_(4)+2KMnSO_(4)+8H_(2)O+10CO_(2)` the pink COLOUR of `KMnO_(4)` DISAPPEARS slowly on treating it with oxalic acid, but the rate of disappearance of colour FASTENS after sometime due to the formation fo `Mn^(2+)` ions which acts as autocatalyst for the reaction.
