Question

Can someone help me design a lab? I'm really confused and would just like help...

Answer 1

lab regarding what topic?

Answer 2

Factors that affect the rate of a reaction

Answer 3

@Somy

Answer 4

can you help? @Somy

Answer 5

oh hmm
what reaction though?

Answer 6

are u referring to cell activity, to be specific, enzyme? proteins? or what is exactly?

Answer 7

here, I'll post the document with the directions.

Answer 8

@Somy

Answer 9

& what are the factors you came up with?

Answer 10

ummm temperature for 1.. I'm not sure what to do for the others..

Answer 11

maybe surface area?

Answer 12

and concentration?..

Answer 13

surface area? how would it effect the rate?

Answer 14

yep concentration would

Answer 15

temperature is good i think
concentration also
hmmm i was thinking if pH could

Answer 16

surface area doesn't? I thought that when you break something into smaller pieces (increasing surface area) the rate of reaction is increased.. but I may be wrong..

Answer 17

true but look at your reactants

Answer 18

they are (aq) meaning aqueous = dissolved in water

Answer 19

so surface area doesnt seem to play role here

Answer 20

ohhhh

Answer 21

also you could use catalyst
see effect on rate

Answer 22

what would be a catalyst tho?

Answer 23

so you can have 3 factors
temperature
concentration
& catalyst

well if you have catalyst - it increases the speed of reaction
no catalyst = speed is lower

Answer 24

but it doesnt interfere with reactants or products
it only finds a route that requires less activation energy and thereby it increases the reaction rate

Answer 25

I know what a catalyst DOES I just don't know what I could use as a catalyst

Answer 26

hmmm dont really know, maybe H2SO4 - its a pretty good catalyst hmmm

Answer 27

would you consider pressure as factor effecting rate of your reaction?

Answer 28

something that I can actually do a lab with at home
and pressure counts, but how would I change pressure?

Answer 29

oh goodness in home condition you say
hmm i gotta check what can u do

Answer 30

that's why it's so hard

Answer 31

uhh temperature, you can do at home, concentration also
but pressure hmmm

Answer 32

oh watch this https://www.youtube.com/watch?v=OttRV5ykP7A
you can get ideas

Answer 33

container
the decreasing or increasing the volume of a container in which the reaction is to occur also effects rate of reaction

Answer 34

how?

Answer 35

well you get a big flask and a smaller one

Answer 36

do the reaction in both flasks
and see the rate at which reaction occurs

Answer 37

ok.. I gotta see if I can buy flasks

Answer 38

hm! since you are doing it at home
just get a small and big bowl
i think it'd do?

Answer 39

@JFraser maybe you could give some ideas?

Answer 40

okay.. omg! I have an idea... jar.. with a lid, that could increase pressure, right?

Answer 41

yes

Answer 42

oh
u could put pressure and not put! ofc!

Answer 43

lol i was trying to think how to decrease the pressure lol so dumb

Answer 44

ummm I talked to my dad about it, and it'll make it explode.. so I can't do that

Answer 45

oh lol
i havent tried any experiments at home with a lid specially so i have no idea how is it gonna go

Answer 46

but well considering the fact that there is release of CO2 gas

Answer 47

yeah it most likely will

Answer 48

so what could I use as a catalyst?..

Answer 49

I gotta eat dinner... I'll back later..

Answer 50

okay, imma think of what could u do there

Answer 51

okay.. thanks.

Answer 52

@Somy have you thought of anything else?.. I'm kinda stuck

Answer 53

nothing is coming to mind T_T

Answer 54

gahhh xc

Answer 55

what about agitation? like stirring?

Answer 56

does that count @Somy?

Answer 57

@somy?

Answer 58

hmm u could use that also

Answer 59

does it count?

Answer 60

but im not sure if you can take that as a factor
but yes it does affect the rate

Answer 61

hmmm well....

Answer 62

the worst that can happen is I get a few points taken off..

Answer 63

thank you so much for your help.. I was overthinking everything and it helped to collab. with someone else, you know? @Somy

Answer 64

@Kainui or @aaronq maybe can help

Answer 65

no problem tho i didnt do much :)
