What are Catalysts used for in a reaction?

By lowering the activation energy, they speed up the reaction and also make it more sustainable and less costly. Also they don't get used up in a reaction, so can be used again.

Speeding up the rate of reaction by providing an alternative route in order to lower activation energy, and the catalyst is not used up during the reaction process too. 

for example enzyme Catalase is a catalyst used for speeding the reaction rate of hydrogen perioxide in order to produce products more quickly. 

Platinum is also used in car exhaust to emit harmless gases e.g. CO2, Water vapor

Advantages: - quickly speeds rate of reaction,

- cost effective as you waste less money on providing for hight temp/high pressure for reaction as exemplified in the Haber Process for the manufacture of ammonia

Speeding up a reaction without getting used - basically lowers activation energy

to speed up the reaction :)

It increases the rate of a chemical reaction. However a true catalyst is not consumed in the reaction.

To speed up reactions, or for efficiany. In simple terms x

a catalyst speeds up reactions without actually getting involved- quite handy really!

catalysts speed up the reaction by providing an alternate route which requires less energy. catalysts are either homoegenous (same phsse to reactants) & heterogenous (different phase) without chemically being used up

they speed up the reaction by bringing the melting point down but they do not affect the result

Takes me back to summer classes in 72, speed up the reaction!

all the best
