Study the data table below showing how temperature affects the rate of a chemical reaction:

Temperature (°C)	Reaction Rate (bubbles per minute)
10	5
20	12
30	25
40	48
50	95
60	15

1. What is the reaction rate at 30°C?

Answer: _________ bubbles per minute

2. At which temperature was the reaction rate highest?

40°C

50°C

60°C

30°C

3. Which data point looks unusual or might be an error? Explain why.

4. What general trend do you notice as temperature increases from 10°C to 50°C?

Reaction rate decreases

Reaction rate increases

Reaction rate stays the same

No clear pattern

5. Complete this conclusion using the data from the table:

Sentence starter: "The data shows that as temperature increases from 10°C to 50°C, the reaction rate ___________________ because ___________________."

6. Why might higher temperatures cause chemical reactions to happen faster?

Particles move faster and collide more often

Particles become heavier

Particles disappear

Particles stick together

7. If you were repeating this experiment, what would you do about the unusual data point at 60°C?

Ignore it completely

Repeat the measurement at 60°C

Check if the equipment was working properly

Record it but note it as unusual

8. Predict what the reaction rate might be at 70°C if the pattern continued normally:

My prediction: _________ bubbles per minute

Explain your reasoning:

9. A student claims: "Temperature doesn't affect reaction rate because the data at 60°C is lower than at 50°C." Explain why this conclusion is incorrect.

Sentence starter: "This conclusion is wrong because ___________________."

10. Why is it important for chemists to collect accurate data in real-world situations? Give one specific example.
