    Most of the transition metals and their compounds particularly oxides have good catalytic properties. Platinum, iron, vanadium pentoxide, nickel, etc., are important catalysts. Platinum is a general catalyst. Nickel powder is a good catalyst for hydrogenation of unsaturated organic compound such as, hydrogenation of oils some typical industrial catalyst is Vanadium pentoxide (V2O5) is used in the Contact process for the manufacture of sulphuric acid.

    Most transition elements act as good catalyst because of:-

    (i) The presence of vacant d-orbitals.
    (ii) The tendency to exhibit variable oxidation states.
    (iii) The tendency to form reaction intermediates with reactants.
    (iv) The presence of defects in their crystal lattices.

    Duvyraj Patidar 8 years ago

    In electrostatics, charge is distributed over the surface of the conductor, therefore the charge inside the conductor is zero so the electric field inside the conductor is zero.
