Catalysts are substances that increase the rate of reaction but can be recovered unchanged at the end of the reaction. catalysts can be classified as either homogeneous (same state as reactants) or heterogeneous (different state than reactants). part a platinum is used to catalyze the hydrogenation of ethylene: h2(g)+ch2ch2(g)−⟶pt(s)ch3ch3(g) chlorofluorocarbons (cfcs) catalyze the conversion of ozone (o3) to oxygen gas (o2): 2o3(g)−⟶cfc(g)3o2(g) magnesium catalyzes the disproportionation of hydrogen peroxide to produce water and oxygen: 2h2o2(aq)−⟶mg(s)2h2o(l)+o2(g) what type of catalysts are platinum, cfcs, and magnesium under these conditions?
