Question 1.
Define a zero-order reaction.
Show hintHide hint
Consider how the rate changes with concentration.
Question 2.
What is the integrated rate law for a first-order reaction?
Show hintHide hint
Recall that this form relates concentrations to time.
3Question 3.
What is the rate law for a first-order reaction?
- Rate = k
- Rate = k[A]
- Rate = k[A]^2
Show hintHide hint
Think about how the rate depends on the reactant.
4Question 4.
True or False: The half-life of a first-order reaction is dependent on the initial concentration of reactants.
- True
- False
Show hintHide hint
Consider how half-life changes with different orders.
Question 5.
A reaction has a rate constant k = 1.5 M/s. Determine how long it will take for the concentration to drop from 8 M to 4 M in a zero-order reaction.
Show hintHide hint
Remember to apply the zero-order integrated rate law correctly.
Question 6.
For a first-order reaction with a rate constant k = 0.1 s^-1, how long will it take for the concentration to decrease from 1 M to 0.5 M?
Show hintHide hint
Use the integrated first-order rate law for calculation.
