hey mate!.......
●CHARACTERISTICS OF CATALYST......
=>(1) A catalyst remains unchanged in mass and chemical composition at the end of the reaction.
(2) A small quantity of the catalyst is generally sufficient to catalyses almost unlimited reactions
(i) For example, in the decomposition of hydrogen peroxide, one gram of colloidal platinum can catalyses litres of hydrogen peroxide.
(ii) In Friedel craft’s reaction, anhydrous aluminium chloride is required in relatively large amount to the extent of 30% of the mass of benzene,
(3) The catalyst can not initiate the reaction: The function of the catalyst is to alter the speed of the reaction rather than to start it.
(4) The catalyst is generally specific in nature: A substance, which acts as a catalyst for a particular reaction , fails to catalyse the other reaction , different catalysts for the same reactant may for different products.

✨Characteristics of catalyst⤵
⏩Catalyst doesn't supply energy.
⏩Mass of catalyst doesn't change during chemical reaction but physical state if catalyst may change during chemical reaction.
⏩Catalyst doesn't take part in chemical reaction. If catalyst takes part in initial step of reaction the. it is escaped out in latter steps.
⏩Catalyst doesn't change energy of reactant, energy of product and Enthalpy of reaction.
⏩Catalyst decreases path or mechanism of reaction.
⏩Catalyst decreases threshold energy and activation energy.
⏩Catalyst increases rate of reaction.
