Question

how would i test if heat increases the rate of reaction

Answer 1

Conduct the same experiment in a Hotter environment.

Answer 2

Welcome to OpenStudy @Trudi222

Answer 3

Can you explain more about conducting the same experiment in a hotter environment

Answer 4

It means that you need to conduct your experiment in different level of temperature. ie, First you start one set of the experiment at room temperature, then you can conduct another set of the same experiment in colder temperature by putting the experiment in ice bath. Then you can move on by putting another set of same experiment in a boiling water condition.

Answer 5

ok and what materials can be used to conduct this ?

Answer 6

are you given the primary set-up of the experiment? or you are setting it up yourself?

Answer 7

setting it up for myself

Answer 8

This is biology right? not chemistry.

Answer 9

yes biology the observation is baking bread during the summer is reduced because the bread rises faster during this period

Answer 10

Ah, then most important thing that you need is the yeast as the main actor. Hurm, is there any specification of materials you need to use. Because to truly see this experiment to work, you need a laboratory materials.

Answer 11

yeast and what else

Answer 12

Are you using household items to set up the experiment or you will use laboratory items?

Answer 13

laborartory

Answer 14

Ok. that is great. For a moment, I couldn't think much of how to conduct experiment using household items.

Materials/apparatus:
Yeast
Corn extract. This is the best solution because yeast use them for fermentation.
Beaker
Durham vial.
Glass rod to mix the extract and yeast.
Water bath of different temperature. Start from lowest around 4C to highest at least 50C depending on your teacher.
Ruler.

Answer 15

ok and what would be the hypothesis ?

Answer 16

The volume of carbon dioxide produce in the durham vial by yeast fermentation will be greater in temperature where yeast function optimally as compare to other temperature ranges.

Answer 17

and what would the method be like

Answer 18

Put the yeast and the extract, mix, invert the durham vial (insert the mix into the durham vial before you invert), let it sit, set up a few of it, best way is to use the test tubes as you can do multiple experiments at the same time. Place the test tubes in different temperature ranges let say, 4C, 8C, 16C, 24C, 32C, 40C, 50C for a period of time maybe 20mins. Take out the test tube, then measured the empty space in the durham vial using a ruler..

Answer 19

and what would be the expected results and interpretation

Answer 20

Well, what do you think?

Answer 21

the yeast to rise

Answer 22

Um no. Anyway, you expect that in 32C, the CO2 volume is greater then other experimental set-up. The interpretation is, you early hypothesis is accepted.

Answer 23

ok so the title for this would be ?

Answer 24

Rate of carbon dioxide production varies in different temperature ranges.
