Does the mass of a catalyst change
Web7.5 Interpret graphs of mass, volume or concentration of reactant or product against time; 7.6 Describe a catalyst as a substance that speeds up the rate of a reaction without altering the products of the reaction, being itself … WebThe surface area to volume ratio of the catalyst may affect the rate. It cannot be precisely controlled, but the same mass of powdered catalyst will have roughly the same surface area to volume ratio.

WebThe sulfuric acid is regenerated. $\ce {HCOOH + H2SO4 -> H2COOH + HSO4- -> H2CO + SO4^ {2-} + H2O -> CO + H2SO4}$. So catalysts do undergo chemical changes in the catalytic reaction but are regenerated after the catalytic reaction is finished. This means that if you are using a catalyst, you can normally reuse it after your catalytic reaction ... WebCatalysts don’t get used up or chemically changed by the reaction. They will be present at the end of the reaction. The mass of the catalyst at the end of the reaction will be the …
