Answer
Usinga thermometer
Explanation
The correct answer is Usinga thermometer. This answer directly addresses the question: Which of the following is NOT a method for investigating reaction rates? It matches the approved Chemistry 8462 learning objective and the linked subtopic. The other options are incorrect because they either change the rate, catalyst, reversible reaction, equilibrium, or graph context, or they do not answer the exact point being tested.
Common mistake
Misunderstanding Practical Methods
Students often confuse collecting gas with measuring mass loss as methods for investigating reaction rates.
Clearly differentiate between the two methods: collecting gas involves measuring the volume of gas produced, while measuring mass loss involves tracking the decrease in mass of reactants.
