Question 1.
What does the rate law express?
Show hintHide hint
Think about the mathematical relationship defined in the section.
Question 2.
If the order of a reaction with respect to reactant A is 1, what happens to the rate if we double [A]?
Show hintHide hint
Consider how the order impacts the reaction rate.
3Question 3.
What does the order of reaction tell us?
- A: It indicates the total time for a reaction to complete.
- B: It indicates how the rate depends on the concentration of reactants.
- C: It shows how temperature affects the reaction.
Show hintHide hint
Think about what the order responds to.
4Question 4.
True or False: A first-order reaction has a linear relationship between reactant concentration and rate.
- True
- False
Show hintHide hint
Recall how first-order reactions behave.
Question 5.
A reaction has a rate law given by Rate = k ⋅ [C]^2 ⋅ [D]^1. What would happen to the rate if [C] is quadrupled and [D] is doubled?
Show hintHide hint
Use the powers of the concentrations to determine the overall impact on the rate.
Question 6.
If a graph plotting ln[A] vs. time shows a linear relationship, can you determine the value of the rate constant if the slope is -0.5?
Show hintHide hint
Recall the relationship between slope and the rate constant for first-order reactions.
