Reaction Rates
What is increasing particle kinetic energy?
What is collide?
What is concentration?
Reaction rate is the change in this over time.
What is remain unchanged?
Catalysts do not get used up in reactions.
What are catalysts?
Enzymes are biological this.
This factor increases reaction rate by providing more reacting particles per volume.
What is activation energy?
What is mol/L*s?
This unit is often used for reaction rate.
What is activation energy?
Catalysts lower this energy barrier.
What is the active site?
This places where the substrate binds.
What is a surface area?
Breaking a solid into smaller pieces increases this.
What is orientation?
Collisions must occur with the correct this.
What is decreasing concentration?
A graph of concentration vs time shows this trend as reactants are used up.
What is reaction pathway?
Catalysts speed up reactions by providing an alternative this.
What is denaturation?
High temperatures can cause this enzymes.
What is pressure?
This factor affects how often particles collide in gases.
What are effective collisions?
Increasing temperature increases this type of collisions.
What is volume of gas?
This can be measured if a gas is produced in a reaction.
What is a heterogeneous catalysts?
This type of catalyst works in a different phases than the reactants.
What is lock and key model?
This model describes enzyme-substrate interaction.
What is refrigeration (low temperature)?
This factor can slow reaction rates in food to prevent spoilage.
What is an ineffective collision?
A reaction where particles collide but do not react is called this type of collision.
What is a spectrophotometer?
This device can measure how fast light absorption changes in a reaction.
What is an inhibitor?
This type of catalyst is a substance that specifically slows down a chemical reaction.
What are proteins?
Enzymes are made of this type of molecule.
