5.6.1.4 catalysts Flashcards
1
Q
What are catalysts?
A
catalysts change the rate of chemical reactions, but are not used up during the reaction. Different reactions need different catalysts
2
Q
In biological terms, what acts as a catalyst?
A
enzymes.
3
Q
Why do catalysts increase the rate of reaction
A
By providing a different pathway for the reaction that has a lower activation energy
4
Q
Draw a reaction profile
A
Energy on left side, progress of reaction underneath.
Obvious labelling of reactants going in and products going out, with visualisation of activation with and without catalysts.
