Catalysts are substances that increase the rate of reaction but
Platinum is used to catalyze the hydrogenation of ethylene:
can be recovered unchanged at the end of the reaction.
Catalysts can be classified as either homogeneous (same
H2(g) + CH2CH2(8)
Pt(s)
CH3CH3(8)
state as reactants) or heterogeneous (different state than
Chlorofluorocarbons (CFCs) catalyze the conversion of ozone (O3) to oxygen gas (02):
reactants).

203(8) -302(8)
Magnesium catalyzes the disproportionation of hydrogen peroxide to produce water and oxygen:
Mg(s)
2H202(aq) – 2H20(1) + 02(g)
