Factor 1: Pressure
How it affects the reaction:
The higher the pressure, the faster the reaction.

Why it affects the reaction in that manner.
The higher the pressure, the closer the particles are and the number of particles per unit volume increases. This increases the frequency of effective collisions, thus increasing the speed of reaction.]]> 2018-06-27 09:54:28 UTC https://padlet.com/barriez/Band_B/wish/268712680 https://padlet.com/barriez/Band_B/wish/269207794 Factor 3: Concentration of Ethanol Solution Formed
How
When the concentration of ethanol is too high, fermentation stops
Why
The high concentration of Ethanol will cause the enzymes in the Yeast to denature, thus stopping the fermentation process

Factor 4: Presence of Yeast
How
Without Yeast, fermentation cannot take place
Why
Yeast contains enzymes, which act on carbohydrates, which acts on sugar and starch, to produce Ethanol and Carbon Dioxide]]> 2018-07-03 01:03:33 UTC https://padlet.com/barriez/Band_B/wish/269207794 https://padlet.com/barriez/Band_B/wish/269207833 Factor 1: Temperature
How: The temperature is around 37 degrees as the speed of reaction is the fastest. 
Why: While any higher than 37 degrees causes the yeast to denature. Any lower the speed will be slower.

Factor 2: Absence of oxygen
How/why: The presence of oxygen causes the Ethanol to be oxidized into Ethanoic acid.]]> 2018-07-03 01:04:10 UTC https://padlet.com/barriez/Band_B/wish/269207833 https://padlet.com/barriez/Band_B/wish/269207840 1-temperature 
How:If temperature is high,enzymes(yeast) would denature.
why: Because the optimal temperature of enzymes is below 40 degrees , if enzymes denature  reaction would not take pace.
3-concentration of ethanol solution formed 
How: High concentration of ethanol kills the yeast.
why:  Yeast cannot live in alcoholic environment.]]> 2018-07-03 01:04:19 UTC https://padlet.com/barriez/Band_B/wish/269207840 https://padlet.com/barriez/Band_B/wish/269207897 Factor 1: Temperature

How it reacts the reaction :
- High temperature will denature the yeast :)
- Low temperature will cause the yeast to be inactive

Why it affects the reaction in that manner :
-  The ideal temperature for the fermentation process is 37 degrees. 
- if the temperature is  too low the yeast cannot work to its optimum, but if its too high the yeast will be denatured. :)]]> 2018-07-03 01:05:11 UTC https://padlet.com/barriez/Band_B/wish/269207897 https://padlet.com/barriez/Band_B/wish/269208148 Factor 2 : Absence of oxygen
How it affects the reaction? :
It slows down the speed of reaction and lesser ethanol will be collected.

Why : With the presence of oxygen, ethanol from fermentation of glucose oxidises to form ethanoic acid.

Factor 3 : Concentration of ethanol formed
How it affects the reaction? :
The higher the concentration of ethanol produced, the slower the speed of fermentation.

Why : This is because the growth of the yeast will be hindered due to high concentrations of ethanol in the solution. Growth of yeast will completely stop when concentration of ethanol formed is high enough. Thus, the number of yeast present reduces, causing the speed of reaction to be slower. Since yeast is a condition for reaction to take place.

How: The higher the concentration of ethanol solution, yeast would be killed and fermentation would not be able to take place.
Why: yeast cannot survive when the concentration of alcohol is too high
Factor 4: presence of yeast
how: the yeast breaks down the sugar to form ethanol and carbon dioxide gas
why: ]]> 2018-07-03 01:08:51 UTC https://padlet.com/barriez/Band_B/wish/269208187 https://padlet.com/barriez/Band_B/wish/269208338 Factor1 & 4

Temp:
The temperature must be at 37 degrees (optimal temp) if not the enzymes will denature

Presence of yeast:
Without the presence of yeast the yeast will not be able to break down the sugar to produce sugar solution.
