Catalyst, in chemistry, any substance that increases the rate of a reaction without itself being consumed. Enzymes are naturally occurring catalysts responsible for many essential biochemical reactions.
How would you describe a catalyst?
A catalyst is a substance that can be added to a reaction to increase the reaction rate without getting consumed in the process. Catalysts typically speed up a reaction by reducing the activation energy or changing the reaction mechanism.
What is a catalyst explain with two examples?
These catalysts speed up chemical reactions but do not change their structure in the process. Examples of inorganic catalysts in chemical reactions include: potassium permanganate – Hydrogen peroxide will decompose into water and oxygen gas. A catalyst of potassium permanganate can be used to speed up this process.
What is a human catalyst?

The most common catalysts used in the water-gas shift reaction are the high temperature shift (HTS) catalyst and the low temperature shift (LTS) catalyst. The HTS catalyst consists of iron oxide stabilized by chromium oxide, while the LTS catalyst is based on copper.
Is Salt a catalyst?
Salt can be considered a catalyst in the reaction but has a different role than most catalysts. Copper II sulfate and aluminum react very slowly because aluminum is coated with a very thin layer of tarnish (aluminum oxide). This reaction can be sped up if the layer of aluminum oxide is removed or compromised.
