Topic 9: Definitions

Question 1

Activation energy

Answer 1

Minimum energy that colliding particles need for a reaction to occur

Question 2

Catalyst

Answer 2

A substance that increases the rate of a chemical reaction by providing an alternate route that is lower in activation energy but is chemically unchanged at the end of the reaction

Question 3

Heterogenouscataylst

Answer 3

A catalyst that is in a different phase to the reactants

Question 4

Max Boltzmann curves know it

Answer 4

Yeah

Question 5

Benefits of heterogeneous catalysts in industrial reactions

Answer 5

• Increase the rate of chemical reaction

* Reactions take place at a lower temp (reducing energy demands)
