Worked Solution & Example Answer:Which one of the graphs best represents the concentration of product C versus time? A - VCE - SSCE Chemistry - Question 5 - 2010 - Paper 1
Step 1
Identify the correct graph
Answer
To determine which graph represents the concentration of product C over time, we must analyze the characteristics of each graph. Product C is typically produced in a reaction, and its concentration would initially increase as the reaction progresses, reaching a steady state.
Looking at the graphs:
- Graph I: This graph shows a sudden increase followed by a plateau, which is characteristic of a product reaching its maximum concentration.
- Graph II: Similar to Graph I, it indicates a sudden jump in concentration but then declines, suggesting that product C is being consumed, which does not align with our expectations.
- Graph III: This graph shows a gradual increase to a plateau with no decline, indicating that the concentration stabilizes at a certain level after production.
- Graph IV: This shows fluctuations which do not accurately represent a stable concentration of product C.
Given these observations, Graph III most accurately depicts the behavior we expect for the concentration of product C over time, being produced and then remaining stable.
