To test the first hypothesis, you measured the reaction rate for several different
The data showed that for higher temperatures, the reaction rate
Hypothesis 2: If you increase the particle size of a reactant, then the reaction rate will increase because more of the reactants’ molecules will contact each other. To test the second hypothesis, you measured the reaction rate for several different
The data showed that for smaller particle sizes, the reaction rate
What would you expect to happen if you raised the temperature of the water to 85°C? Check all that apply.The reaction rate would be faster than the rate at 65°C.The reaction rate would be slower than the rate at 0°C.The reaction rate would be equal to the rate at 65°C.The reaction rate would be slower than the rate at 95°C.

The longer the reaction time is, the the reaction rate is. Reaction time is to reaction rate.
Your stomach is upset. You want relief – and fast! What actions could you take to speed up the reaction of the tablet? Check all that apply.heating the water even morecooling the water downusing half a tabletbreaking the tablet into smaller piecesdecreasing the amount of waterheating the water and breaking the tablet at the same time
Why was the weigh/filter paper used in this experiment? Check all that apply.to weigh the tabletto make sure that all of the broken pieces of tablet were added to the waterto prevent the tablet from absorbing waterto allow for fair comparison of all three trials, with different particle sizesto avoid experimental errorto ensure that the entire tablet is present, since otherwise it would not dissolve
Suppose that a student did not stop the timer as soon as bubbling stopped during a test at 40°C. Check all possible resulting errors.Measurements at all temperatures will have errors.The reaction time will be too long.The reaction time will be too short.The reaction time will resemble the reaction time for a higher temperature.The reaction time will resemble the reaction time for a lower temperature.
Reptiles, amphibians, and fish are all cold-blooded animals. Their body temperatures are determined by their surroundings. How does a cold-blooded animal’s ability to digest food change in colder temperatures?It digests food at the same rate regardless of the temperature.It digests food more quickly at lower temperatures.It digests food more slowly at lower temperatures.
The longer the reaction time is, the the reaction rate is. Reaction time is to reaction rate.
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.Some of the broken tablet was not added to the water.The tablet was not crushed enough to make a substantial difference.The size of the reaction beaker was varied.The tablets were not uniform in their mass.

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