catalyst and activation energy Flashcards
1
Q
what do catalysts do
A
it provides an alternate reaction pathway with a lower activation energy. because the activation energy is lower, more particals have enough energy to react so the reaction is quicker and greater
2
Q
why is iron a good catylyst
A
its cheap and doesn’t react, it doesn’t need to be repalced because it doesn’t get used up and it’s in small lumps because the surface area is increased
3
Q
what is a catylyst
A
a chemical that takes part in a reaction but doesn’t get used up
4
Q
what’s the most affective catalyst
A
copper
5
Q
what is activation energy
A
the minimum amount of energy that must be provided for compounds to result in a chemical reaction.
6
Q
why does surface area mean the reaction is affected
A
higher the surface area- more likely to collide
