Use the Internet to find out what chemical reaction takes place in a catalytic converter. The compound H 2 PtCl 6 may be involved. Write the equation for the chemical reaction that takes place in a catalytic converter. Write at least one paragraph explaining how the catalytic converter reduces air pollution. Physical Science Activation energy is the energy needed to start a chemical reaction.
All chemical reactions require energy to begin.
Enough energy is available from the environment to start some reactions. For others, additional energy must be added before the reaction will begin. When sodium metal reacts with water, heat is produced.
