2 cards from this section. Quick, good the night before a test.
What is activation energy?
Think about the energy barrier needed to start a reaction.
What role does a catalyst play in a chemical reaction?
What happens to the energy required for the reaction?
What is the primary function of a catalyst in a chemical reaction?
Think about what catalysts do to energy barriers.
True or False: Catalysts are consumed in a reaction.
Remember what happens to a catalyst at the end of a reaction.
Using the Arrhenius equation, calculate the rate constant k if the activation energy is 50 kJ/mol at a temperature of 300 K.
Remember to use the gas constant R in proper units.
Design an experiment to compare the reaction rates of a catalyzed vs. uncatalyzed reaction. Outline your procedure and discuss the expected outcomes.
What measurements would best demonstrate the difference in rates?
