Given :
$E_{{x^{ + 2}}/x}^o = - 1.36\,volt$ ;
$E_{{y^{ + 2}}/y}^o = - 0.76\,volt\,\frac{{2.303\,RT}}{F} = 0.06$
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.
