Question 1.
What is the initial rate in a reaction?
Show hintHide hint
Think about when you start observing the reaction.
Question 2.
How does varying the reactant concentration relate to the reaction rate?
Show hintHide hint
Consider how changing one variable can affect another in an experiment.
3Question 3.
What does the initial rates method help chemists determine?
- The final product
- The order of the reaction
- The reaction temperature
Show hintHide hint
Consider what aspect of the reaction this method focuses on.
4Question 4.
True or False: The concentration of all reactants must be changed simultaneously to determine reaction order.
- True
- False
Show hintHide hint
Think about the importance of controlling variables.
Question 5.
Design an experiment to determine the reaction order of a hypothetical reaction A + B → C. Explain how you would systematically vary concentrations and analyze results.
Show hintHide hint
Think of how controlling variables can help isolate reactions.
Question 6.
Given the following data from initial rate experiments: Experiment 1: [A]=0.1 M, [B]=0.2 M, Rate=0.01 M/s; Experiment 2: [A]=0.1 M, [B]=0.4 M, Rate=0.04 M/s; Analyze the data to determine the order of reaction with respect to B.

Look for multiplicative relationships in rates when concentrations change.
