In the previous blog post, we have watched a video on 5 factors that can affect the rate of a chemical reaction.
Today, we shall discuss the role of a suitable catalyst and how it increases the rate of a chemical reaction.
Many of my students in our Sec 4 GCE O-Level Pure Chemistry tuition classes always share with us that their friends have difficulty to score full marks in Chemistry Examinations whenever they were being asked about how a catalyst work to increase the rate of reaction.

Some key points from the video:
- A catalyst is a substance which increases the speed of a chemical reaction and remains chemically unchanged at the end of the reaction
- A catalyst increases the speed of a reaction by providing an alternative pathway with a lower activation energy
- In a catalysed reaction, more colliding particles possess energy equal to or greater than the activation energy and hence the speed of reaction is higher
