Catalyst

Q. Platinum is used to catalyze the hydrogenation of ethylene: H2(g) + CH2CH2(g) → CH3CH3(g) Chlorofluorocarbons (CFCs) catalyze the conversion of ozone (O3) to oxygen gas (O2): 2O3(g) → 3O2(g) 2H2O2(aq) → 2H2O(l) + O2(g) What type of catalyst are platinum, CFCs, and magnesium under these conditions? Drag the appropriate items to their respective bins

Catalyst

Q. The graphs shown here are called potential energy diagrams. They show the potential energy of a system as it changes from reactants to products. The first graph shows the uncatalyzed reaction (figure 1); the second graph shows the catalyzed reaction (Figure 2). How does the presence of a catalyst affect the activation energy of a reaction?
