Given below are two statements for catalytic properties of transition metals :
Statement I : First row transition metals which act as catalyst utilise their 3d electrons only for formation of bonds between reactant molecules and atoms on the surface of catalyst.
Statement II : There is increase in the concentration of reactants on the surface of catalyst which strengthens the bonds in reacting molecules.
In the light of the above statements, choose the correct answer from the option given below :
Text Solution
Verified by ExpertsB
First row transition metals utilize 3d and 4s electrons for bonding on the catalyst surface.
∴ Statement 1 is incorrect
Adsorption increases reactant concentration on the catalyst surface and weakens bonds facilitating formation of activated complex and lowering activation energy.
Statement 2 is incorrect
