Module 2

• This is a process of speeding up a reaction by using catalyst. CATALYSIS
• This occurs when a catalyst and the reactants are in the same physical state. HOMOGENEOUS CATALYSIS
• This is known as the catalyst in all living system. ENZYMES
• Catalyst will not affect the degree or the process of the reaction. TRUE
• The rate of reaction can be increased if we increase the temperature. TRUE
• Heterogeneous catalysts are catalysts with the same phase as the reaction mixture. FALSE
• Enzymes are responsible for may essential biochemical reactions. TRUE
• Catalytic action forms chemical reactions that are able and ready to react with one another forming reactants. FALSE
• A common heterogeneous catalyst mostly includes organic solids. FALSE
• The lower the transition state energy, the lower the activation energy. TRUE
• Most enzyme lowers the activation energy of a chemical reactions. TRUE
