10.2 Catalysts Flashcards
1
Q
what is a catalyst?
A
lowers the activation energy in a reaction without being used up
2
Q
what are the two types of catalyst?
A
homogeneous
heterogeneous
3
Q
what is a homogeneous catalyst?
A
a catalyst which is the physical state as the reactants
4
Q
what is a heterogeneous catalyst?
A
a catalyst which is a different physical state to the reactants
5
Q
why are catalysts important in industry?
A
by lowering the activation energy less temperature is needed for reactions and so less energy is needed
with less energy needed, less fossil fuels are used
also increases reaction rate which means faster production
6
Q
why are catalysts useful for the environment?
A
using a catalyst means less fossil fuels needed
so less CO2 produced
