◼It can either speed up or can slow dowm the reaction.
◼It can be regained after the reaction had been conpleted as it remains unaffected.
◼It can be used as an source to provide heat, after an eternal heating is done.
Example :-
▶During catalytic oxidation of Ammonia,
heating is done innitally and further platinum which was used as catalyst carries on emiting heat .
▶During preparation of sulphuric acid on contacts process venadium pentaoxide is used as catalyst to increase the rate of reaction in conversion of sulphur dioxide to sulphur trioxide.
