Hint:Catalysts are those substances which when added to a reaction, increases the rate of the reaction. There are two types of catalysts, homogeneous catalysts and heterogeneous catalysts. Heterogeneous catalysts are not in the same phase with its reactants and products.

Complete step by step solution:
Heterogeneous catalysts are those catalysts which are not in the same phase with their reactants and products. Such a reaction where the reactants, products and the catalysts are in different phases is called heterogeneous catalysis.
> In the given equation, it is mentioned that the reactants (\[S{{O}_{2}}\] and\[{{O}_{2}}\]), the product \[S{{O}_{3}}\] and the catalysts NO all are in gaseous phase. Therefore we can conclude that the catalysis is homogeneous and the catalyst NO is a homogeneous catalyst.
So we have to enter 0.
> In some cases heterogeneous catalysis is also known as surface catalysis, when the catalyst is solid and the reactants are gases. The mechanisms of such catalysts are not yet known properly, but certain sites in the catalyst surface have the ability to weaken or break a bond. Such sites are called active sites. An example of a heterogeneous catalyst is the catalytic converter in gasoline or diesel-fueled cars. In petroleum industries heterogeneous catalysts are of high demand. In Haber process (synthesis of \[N{{H}_{3}}\] from \[{{N}_{2}}\]and\[{{H}_{2}}\]) finely divided Iron is used as a catalyst, which is a heterogeneous catalyst. It also has its uses in the automobile industry.

Note: While answering this type of questions we have to check whether the catalysts, reactants and the products are in the same phase. If they are different phases it is heterogeneous catalysts and all are in the same phase, then the catalyst is a homogeneous catalyst.
