Question

Which is not true for describing the catalytic activity of transition metals?

• A. Their ability to adopt multiple oxidation states
• B. Their ability to form bonds between reactant molecule and atoms of the surface of catalysts
• C. Increasing the concentration of reactants at the catalyst surface
• D. Strengthening the bonds in the reacting molecules

Answer 1

Answer: (D)

Catalytic activity of transition metals defiends upon their ability to show variable (multiple) oxidation states and to form bonds with the reactant molecules, however not on the strength of the bonds formed. Further, increased concentration of reactants at the surface of the catalyst reduces the activity of catalyst
