प्रश्न
Which of the following characteristics of transition metals is associated with their catalytic activity?
विकल्प
Paramagnetic nature
Colour of hydrated ions
High enthalpy of atomisation
Variable oxidation states
उत्तर
Variable oxidation states
Explanation:
Transition metals have a tendency to have varying oxidation states, which allows them to create unstable intermediates and provide a novel reaction path with a lower Ea. As a result, transition metals have catalytic activity.
