The Activation Energy is Lowered by Catalysts Flashcards
1
Q
What does the activation energy represent?
A
The minimum energy needed by reacting particles for the reaction to occur
2
Q
How does a catalyst make reactions happen faster?
A
By providing an alternative reaction pathway with a lower activation energy
3
Q
Use of catalyst - how is this represent on the diagram?
A
By the Lower curve, which shows that less initial energy is needed for the reaction to begin
4
Q
What happens to the overall energy change for the reaction ΔH?
A
It remains the same
5
Q
See graph page 60
A
Ok
