6 sample questions

Question 1.
Define initial rate.
Show hintHide hint
Think about the timing in the reaction.
Question 2.
What does it mean when a reaction is first order?
Show hintHide hint
Consider how concentration affects speed.
3Question 3.
What is the initial rate of a reaction?
- Speed at high concentrations
- Speed at the beginning of a reaction
- Slowest point in the reaction
Show hintHide hint
Focus on timing in regards to the reaction.
4Question 4.
True or False: A zero order reaction's rate is dependent on the reactant concentration.
- True
- False
Show hintHide hint
Reflect on how concentration variations affect speed.
Question 5.
You conduct an experiment showing that when [A] is doubled, and the rate increases by a factor of 2, while when [B] is doubled, the rate increases by a factor of 4. Determine the orders of the reaction with respect to [A] and [B] and write the rate law.
Show hintHide hint
Analyze how each change in concentration impacted the rate.
Question 6.
During a reaction study, you notice that doubling the concentration of a reactant doesn't change the initial rate. What can you conclude about the reaction order with respect to that reactant, and why?
Show hintHide hint
Reflect on the independent characteristics of zero-order reactions.
