Question
- A. It decreases the rate of reaction
- B. It has no effect on the rate of reaction
- C. It increases the rate of reaction
- D. It only affects solid reactants
Answer
It increases the rate of reaction
Explanation
The correct answer is It increases the rate of reaction. This answer directly addresses the question: What is the effect of increasing the concentration of a solution on the rate of reaction? 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 Graph Gradients
Students often confuse the steepness of the graph with the amount of product formed, rather than understanding it represents the rate of reaction.
Focus on how the steepness of the graph indicates the speed of the reaction, where a steeper gradient means a faster rate of reaction.
