Why does V2O5 act as catalyst?

Transition metal has availability of vacant d- orbital Due to which transition metal show variable oxidation state.  Vanadium is transition metal and it easily changes from one oxidation state to another. It can form unstable intermediates in one oxidation state and then readily changes into products by acquiring another stable oxidation state and thus providing new path to reaction.
