NEET Chemistry Surface Chemistry Questions Solved

BOARD

Name the two groups into which phenomenon of catalysis can

be divided. Give an example of each group with the chemical

equation involved.

Homogeneous catalysis: When the reactants and the catalyst are in

the same phase, the process is called homogeneous catalysis.

Example: $2{\mathrm{SO}}_{2}\left(\mathrm{g}\right)+{\mathrm{O}}_{2}\left(\mathrm{g}\right)\stackrel{\mathrm{NO}\left(\mathrm{g}\right)}{\to }2{\mathrm{SO}}_{3}\left(\mathrm{g}\right)$

Heterogeneous catalysis: When the reactants and the catalyst

are in different phases, the process is called heterogeneous

catalysis.
