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? drag the appropriate items to their respective bins.
Catalysts lower the activation energy of a chemical reaction. Catalyst is a substance that speeds a chemical reaction. It is not consumed as the reaction proceeds. A catalyst offers a new route for faster reaction. Catalysts are classified as homogeneous ( same state as the reactants ) or heterogeneous (different state as the reactants). Platinum would be a heterogeneous catalyst. CFCs would be a homogeneous catalyst. Magnesium would be a heterogeneous catalyst.
The reaction for what was describe in the problem is:
N₂ + 3 O₂ --> 2 NO₃
The reactants involved are nitrogen and oxygen gas. From the word itself, oxygen is an oxidizing agent. <em>Therefore, this reaction is an oxidation reaction due to the presence of the oxidizing agent.</em>
