Question

What is a reaction that uses a catalyst?

Answer 1

Catalyst: Substances that change the rate of a chemical reaction and themselves remain chemically unchanged after the reaction are called catalysts.

Example:- In the process of manufacturing of ammonia Fe is used as Catalyst.

`N _(2) (g)+ 3H _(2) (g) \huge \rightarrow {}^(Fe)\rightarrow \small{3NH _(3)(g)}`

Note:- there is only one arrow. I was unable to put iron over the arrow ..

Answer 2

One of the most commonly known catalysed reaction is that of Hydrogen Peroxide turning into Water

In this reaction, we can use Potassium Permanganate (KMnO₄) or Palladium (Pd) as a catalyst.

These catalysts helps Hydrogen Peroxide turn into water and oxygen
