Rate of Reaction Between Hydrogen Peroxide and the Potato
Prediction
The predictions for the rate of reaction, between the Hydrogen
Peroxide and the potato.
For this experiment there are some vital factors referred to the rate
of reaction between the hydrogen peroxide and potato slice. For this
experiment I will predict what the affect of the concentration,
particle size and temperature would be.
The Concentration:Would a low concentration be better for the
experiment or a high concentration? If there was an experiment taking
place with a low concentration then the particles would be more spread
out, this results in fewer collisions, so therefore there will be a
result of fewer successful collisions. Which will then make the
reaction taking place speed go slow, so there would be a graph with a
rather slow reaction taking place. If I was to do the experiment with
a high concentration the particles are crowed close together and
therefore it would collide with each other more often, which will give
me a result of successful collisions. So for my experiment I predict
that the concentration would be high with successful collisions.
Different potatoes may have different concentrations of enzymes; if I
use an old potato this may loss its concentration of enzyme due to
age. So I predict that an old potato would cause a loss of
concentration which will cause a lot of problems within the
experiment. So therefore it would be better if I used a new potato and
the same potato throughout the experiment.
Hydrogen Peroxide may also affect the concentration; hydrogen peroxide
decomposes at room temperature so if I leave it outside at room
temperature this may affect the concentration of the hydrogen
peroxide.
In a low concentration the reaction would be slow because of fewer
collisions.

With a high concentration the reaction would be faster because of more
collisions.

I predict that my reaction will be fast due to high concentration.

What Affects the Rate of Breakdown of Hydrogen Peroxide by Enzymes Aim = == The aim of this experiment is to find out how temperature and concentration affect the breakdown of hydrogen peroxide by an enzyme (yeast). I hope to achieve reliable results that will confirm my predictions.
The Effect of a Catalase on the Breakdown of Hydrogen Peroxide Aim To follow the progress of a catalysed reaction by measuring the volume of gas produced as the reaction proceeds. Using the initial rates of a series of experiments I will be able to find the orders of the reaction with respect to enzyme and substrate. Also to find out if concentration has an effect on the reaction when an enzyme is used to accelerate the breakdown of hydrogen peroxide.
