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.
Solution
Reactants must not get adsorbed so strongly
that they are immobilised and other reactants
are left with no space on the catalyst’s surface
for adsorption.
