Triumph Chemistry Multiple Choice Questions


Classical Thinking
1. Surface or interface represents the boundary which separates two bulk phases.
4. Rate of adsorption is rapid in the beginning and falls as time passes.
9. The extent of adsorption is large at low temperatures and decreases as the temperature is raised.
10. Adsorption of hydrogen on glass is endothermic because hydrogen dissociates.
11. Adsorption of H2 on Ni is physical adsorption at low temperature and becomes chemisorption at higher
13. Freundlich’s adsorption isotherm is given by
15. Activation energy changes when the catalyst is used in a reaction.
Catalyst and reactants exist in the same phase in homogeneous catalysis.
19. SO2 and O2 are gases whereas V2O5 is a solid, hence the reaction in option D is heterogeneous catalysis.
20. Finely divided metals like Ni, Pd or Pt are used as a catalyst during the hydrogenation of unsaturated vegetable
21. Finely divided matter provides a much larger surface area, compared to its solid state. Thus, a catalyst in the finely
divided state is more efficient.
23. The product in the presence of Pd/Al2O3 catalyst is acetaldehyde while in the presence of Ag/Al2O3 catalyst, the
product is ethylene oxide.
