The ability of a catalyst to accelerate the chemical reaction is known as

In the reaction,$H_2O_{2(aq)} \xrightarrow{I^{-}_{(aq)}} H_2O_{(l)} + \frac{1}{2} O_{2(g)}$,the iodide ion acts as:

Zeolites are:

In the oxidation of oxalic acid by $KMnO_4$,the color of $KMnO_4$ disappears slowly at the beginning of the reaction,but then it disappears very rapidly. This is an example of .......

What is the role of desorption in the process of catalysis?

The following reaction is catalyzed by $Br^-_{(aq)}$: $2H_2O_{2(aq)} \rightarrow 2H_2O_{(l)} + O_{2(g)}$. What type of catalysis is this?
