    Which of the following leaction is an example for homogeneous catalysis?

    A)  \[2{{H}_{2}}{{O}_{2}}(l)\xrightarrow{Mn{{O}_{2}}(s)}2{{H}_{2}}O(l)+{{O}_{2}}(g)\]

    B)  \[2S{{O}_{2}}(g)+{{O}_{2}}(g)2S{{O}_{3}}(g)\]

    C)  \[2CO(g)+{{O}_{2}}(g)\xrightarrow{NO(g)}2C{{O}_{2}}(g)\]

    D)  \[{{H}_{2}}(g)+{{C}_{2}}{{H}_{4}}(g)\xrightarrow{Ni(s)}{{C}_{2}}{{H}_{6}}(g)\]

    Correct Answer: C

    Solution :

                    When the reactants and catalyst are in the same phase, the catalysis is known as homogeneous.     \[2CO(g)+{{O}_{2}}(g)\xrightarrow[{}]{NO(g)}2C{{O}_{2}}(g)\] In this reaction both reactant and catalyst are in the gaseous phase.
