    Following reaction is catalysed by\[B{{r}^{-}}(aq)\].                 \[2{{H}_{2}}{{O}_{2}}(aq)\xrightarrow{{}}2{{H}_{2}}O(I)+{{O}_{2}}(g)\] This is an example of

    A)  homogeneous catalysis

    B)  heterogeneous catalysis

    C)  autocatalysis

    D)  enzyme catalysis

    Correct Answer: A

    Solution :

    When the reactants and the catalyst are in same phase, the catalysis is homogeneous. Reactant:\[{{H}_{2}}{{O}_{2}}\]; Phase :\[(aq)\] Catalyst:\[B{{r}^{-}}\];   Phase\[(aq)\] Hence, it is an example of homogeneous catalysis.
