Lab: Reaction Rate

Question 1

Suppose that a different student obtained reaction rates for the particle-size experiment, and that these rates did not show a pattern. Check all possible sources of this error.

Revolt · Accepted Answer

Some of the broken tablet was not added to the water.; The tablet was not crushed enough to make a substantial difference.; The tablets were not uniform in their mass.

Question 2

The smaller the particle size, the the surface area. Therefore, particle size is to surface area.

Revolt · Accepted Answer

greater; the surface area. Therefore, particle size is: greater; to surface area.: inversely proportional

Question 3

To test the second hypothesis, you measured the reaction rate for several different volumes.temperatures.densities.✔ particle sizes.

Revolt · Accepted Answer

particle sizes.

Question 4

The smaller the particle size, the lesser✔ greaterthe surface area. Therefore, particle size is

Revolt · Accepted Answer

greater; Selection 1: greater; Selection 2: inversely proportional

Question 5

The data showed that for smaller particle sizes, the reaction rate ✔ increases.decreases.does not change.fluctuates randomly.

Revolt · Accepted Answer

increases.

Question 6

proportional✔ inversely proportionalequal to surface area.

Revolt · Accepted Answer

inversely proportional
