Question 1.
What is chemical kinetics?
Show hintHide hint
Think about how we measure reaction speeds.
Question 2.
What is activation energy?
Show hintHide hint
Consider the energy barrier for a reaction.
3Question 3.
What does chemical kinetics study?
- The energy of reactions
- The rates of reactions
- The equilibrium of reactions
Show hintHide hint
Think about how fast something happens.
4Question 4.
True or False: Activation energy is the maximum energy required for products to form.
- True
- False
Show hintHide hint
Do you remember the definition of activation energy?
Question 5.
A reaction has an activation energy of 50 kJ/mol. How will increasing the temperature influence the reaction rate?
Show hintHide hint
Think about how temperature affects molecule speed.
Question 6.
If increasing concentration doubles the reaction rate, what can be inferred about the reaction order with respect to that reactant?
Show hintHide hint
Consider how concentration changes affect the rate.
