Does catalyst change the amount of product
WebAdding a catalyst has exactly this effect of shifting the activation energy. A catalyst provides an alternative route for the reaction. That alternative route has a lower activation energy. Showing this on an energy profile: A word of caution! Be very careful if you are asked about this in an exam. The correct form of words is WebSep 19, 2024 · A catalyst affects a chemical reaction by accelerating it.

WebCatalysis A catalyst speeds up a reaction by lowering the activation energy required for the reaction to proceed. To reiterate, catalysts do not affect the equilibrium state of a reaction. In the presence of a catalyst, the same amounts of reactants and products will be present at equilibrium as there would be in the uncatalyzed reaction. WebWe did few reactions using catalyst and observed that reaction getting faster with increasing concentration of catalyst. i.e using for 10%w/w catalyst reaction completed in 2h where as for 5%w/w ...
