Select the wrong statement.

AThe reducing power of $$H_2$$ is increased if it is absorbed on $$Pd$$.
BThermite welding does not require a catalyst.
CThe decomposition of $$H_2O_2(l)$$ in presence of $$Hg(l)$$ is homogeneous catalysis.
Correct Answer
DThe chemical adsorption requires activation energy.

Solution

$$\begin{array}{l}\text{ The decomposition of }\mathrm{H}_{2}\mathrm{O}_{2}(\mathrm{l})\text{ is heterogenous }\text{catalysis because }\mathrm{O}_{2}(\mathrm{~g})\text{ is formed in }\\\text{ the chemical reaction which is in gaseous }\text{ state .}\end{array}$$
