2 cards from this section. Quick, good the night before a test.
What is activation energy?
Think about what is required for a reaction to get started.
Give an example of a catalyst.
Consider substances that speed up reactions.
What is the minimum energy required for a reaction?
Consider the term used when discussing energy barriers.
True or False: Catalysts are consumed during a reaction.
Think about what happens to catalysts after they speed up a reaction.
Given that two reactions have activation energies of 50 kJ/mol and 100 kJ/mol respectively, discuss how this difference affects their rates at room temperature.
Consider how temperature influences the energy distribution of particles.
If a catalyst lowers the activation energy by 20 kJ/mol, how does this affect the reaction rate? Calculate the rate increase if the original rate is known.
Think about how lowering the energy barrier impacts the number of particles successfully initiating the reaction.
