In this investigation I leave be trying to find out if the regularise of a
reaction changes if the stringency of the warmheartedness is altered.
This allow for go along if the Hydrogen peroxide is decompostured.
Hydrogen peroxide (H202) is a clear reprehensible liquid, which is
produced during respiration. If this builds up inside the body it can
kill, so an enzyme called CATALASE shekels this from happening by
breaking down the build up. to a greater extent about Hydrogen Peroxide will be
explained in my knowledge. The decomposition of Hydrogen peroxide
looks like this:

Prediction
==========
I think that the higher the concentration of Hydrogen Peroxide, the
more bubbles will induce out. The purer the Hydrogen Peroxide, the
quicker the reaction rate. Because I am going to change the
concentration of Hydrogen Peroxide after each experiment, I think that
fewer bubbles will come out. This is because there will be little
Hydrogen Peroxide in the beaker so there will be less to decompose.
I also think that if I double the Concentration, I will see twice the
number of bubbles, and if I furcate the Concentration by 2, I expect to
see half(prenominal) the number of bubbles (e.g.-Concentration 2 molar, 36
bubbles, Concentration 1 molar, 18 bubbles).
This can be seen in the
graph below.
My Knowledge
------------
Reactions happen all the magazine all around us e.g. a balloon bursting, a
cake baking, an apple ripening and discharge a fire. Some of them are
very slow, while rough are very fast. Different reactions have
different rates. The rate of a chemical reaction is the speed or time
taken for it to happen.
The majority of chemical reactions are faster when the concentration
is
higher. This is because at a higher concentration, the molecules in a
substance have more kinetic energy, which means they will carry around
quicker. This makes it easier for them to react together. When...If you want to get a affluent essay, order it on our website: Orderessay
