For the following Assertion and Reason, the correct option is:
Assertion: For hydrogenation reactions, the catalytic activity increases from Group 5 to Group 11 metals with maximum activity shown by Group 7-9 elements.
Reason: The reactants are most strongly adsorbed on group 7-9 elements.
Correct Option: 1
Reactant should not be adsorbed strongly which might result into immobilisation that inhibit further adsorption on the catalyst's surface.
