Differentiate between homogenous and heterogenous catalysis with one example of each . |
|
Answer» Solution :In the homogenous catalysis , the reactants and the catalyst ara all present in the same phase. But in heterogenous catalysis , these constitute difference phases . For example : (i) Oxide of nitrogen (NO) acts as homogenous catalyst in the oxidation of `SO_2` to `SO_3` in the contactprocess ` 2SO_2 + O_2 overset(NO_2)(to) 2SO_3` (II) Nickel (Ni) acts as the heterogenous catalyst in the reaction of steam on METHANE of form carbon monoxide and hydrogen . `CH_4 + H_2O UNDERSET(1273 K)overset(Ni)(to) underset("steam")(CO + 3H_2) ` |
