How can the rate of the chemical reaction namely decomposition of hydrogen peroxide be increased ? |
|
Answer» (i) The chemical reaction in which two or more products are formed from a single reactant is called decomposition reaction. Hydrogen peroxide decomposes into water and oxygen. `{:(2H_(2)O_(2(l))to 2H_(2)O_((l))+O_(2)uarr),("Hydrogen" " ""Water" " ""Oxygen"),("peroxide"):}` (ii) The decomposition of hydrogen peroxide into water and oxygen takes place slowly at room temperature. However, the rate of this chemical reaction can be increased on adding manganese dioxide `(MnO_(2))` powder in it, here manganese dioxide acts as a catalyst. |
