Energy Changes in Chemical Reactions + Energy Profile Diagrams + The role of Catalysts Flashcards
1
Q
What are catalysts?
A
- substances that increase the rate of a chemical reaction
- without being used up or chemically changed
2
Q
How do catalysts work?
A
they create an alternative reaction pathway by forming and breaking different chemical bonds
3
Q
What is the difference between a catalytic and a non-catalytic pathway?
A
Catalytic pathways have a lower activation energies
4

A
a reaction in which one or more of the reactants and products in a different phase to the reactants
