Experiment to observe how rate of reaction depends on the surface area.
Experiment to observe how rate of reaction depends on the surface:
I) Aim:
Prove that the rate of reaction depends on the surface.
II) Hypothesis:
Smaller the particle size is, faster the reaction will be completed; because when things are smaller, they are completed quicker.
III) Materials:
- 4 beakers
- 1 timer
- 1 frizzy tablet
- 1 knife
- 1 thermometers
- 600 ml of water
- lab coat and safety goggles
IV) Method:
- We cut the frizzy tablet in quarters.
- We put 150cm3 of water in a beaker.
- We put the quarter of frizzy tablet in it.
- We time the reaction and we measure the temperature.
- Then we put another 150cm3 of water in a beaker.
- We cut the second quarter in four pieces and then we put it in the beaker.
- We time the reaction and we measure the temperature.
- Then we put another 150cm3 of water in a beaker.
- We cut the third quarter into tiny piece and then we put it in the beaker.
- We time the reaction and we measure the temperature.
- Then we put another 150cm3 of water in the beaker.
- We take the last quarter and crush it until it is powder.
- We put the powder in the beaker.
- We time the reaction and the temperature.
