Multiple Choice
How does reducing the time allowed between classes help increase the rate of collisions?
Students will have more time to socialize and collide with each other
Students will have more time to prepare for the dance
Students will have more opportunities to study chemistry between classes
Students will move more quickly, resulting in collisions with higher energy
3
Multiple Choice
What is the main similarity between colliding with someone and knocking the books out of their hands and a chemical reaction?
Both require a high temperature to occur
Both involve the use of a catalyst
Both involve the breaking up of clumps into individual particles
Both require the correct orientation and enough energy
4
Multiple Choice
How does increasing the temperature of a reaction mixture affect the rate of a chemical reaction?
It increases the rate of the reaction
It has no effect on the rate of the reaction
It depends on the specific reaction being studied
It decreases the rate of the reaction
5
Multiple Choice
What is the purpose of a chemical catalyst in a reaction?
To increase the concentration of reactants
To decrease the overall population of the reactants
To increase the activation energy of the reaction
