Let's analyze the table and questions step by step.
1. Understanding the Given Data:
| Type of Water | Volume (mL) | Temperature (°C) | Average Time (s) |
|-----------------|-------------|------------------|------------------|
| Hot water | 250 | 40 | 22 |
| Room temperature| 250 | 20 | 51 |
| Cold water | 250 | 4 | 86 |
2. First Question:
As the temperature of the reaction increases, what happens to the average time for the tablet to dissolve?
- Let's observe the temperatures and average times in the table:
- At 40°C: the time is 22 seconds.
- At 20°C: the time is 51 seconds.
- At 4°C: the time is 86 seconds.
The pattern shows that as the temperature increases, the time taken for the tablet to dissolve decreases.
Therefore, the average time for the tablet to dissolve decreases as the temperature increases.
3. Second Question:
A shorter time of reaction indicates a _____ rate of reaction.
- Given the relationship identified above, a lower average time means the process happens more quickly. This implies a higher rate of reaction.
Therefore, a shorter time of reaction indicates a faster rate of reaction.
Combining these conclusions, we determine:
- As the temperature of the reaction increases, the average time for the tablet to dissolve decreases.
- A shorter time of reaction indicates a faster rate of reaction.
