Answer
collectinggas produced
Explanation
The correct answer is collectinggas produced. This answer directly addresses the question: Which method can be used to investigate the effect of concentration on reaction rate? 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 Investigation Methods
Students often describe methods for investigating reaction rates without specifying how to control variables.
Emphasize the importance of controlling variables such as temperature, concentration, and surface area to ensure valid results.
