TITLE OF EXPERIMENT: An investigation of the iodine/propanone reaction.
DATA COLLECTION AND PROCESSING :
CH3COCH3 (aq) + I2 (aq) ( CH3COCH2I + H+ (aq) + I- (aq)
Rate of reaction:
R = V
Concentration of reactant after dilution :
The reaction rate of a chemical reaction is determined as the change in the concentration of a reactant or product over the change in time.  The rate of a reaction is determined by experiment. Many factors influence the rate of a reaction: the nature of the reaction,...
After having built up knowledge about the kinetics of reactions I decided to do an investigation in this area. I was initially introduced to this particular reaction1 in EP6.4 and then in AA2.1. I was interested in using this reaction as a means of potentially supporting and q

Using the Iodine clock method to find the order of a reaction
When peroxodisulfate (VI) ions and iodide ions react together in solution they form sulfate (VI) ions and iodide. This reaction is shown below:
S2O82-aq+ 2I-aq SO42-aq+ I2(aq)
The reactants and the sulfate (VI) ions are
The Iodine Clock Investigation
This is an investigation into the rate of a reaction and the factors
that contribute to how fast a reaction will take place. Through the
recording and analysis of raw data, this investigation also allows us
to apply generally accepted
factors affecting the kinetics of reaction between peroxodisulfate (vi) and iodide

Kinetics of the Reaction between Acetone and Iodine
The key aim of this experiment was to determine the rate equation for the acid-catalysed iodination of acetone and to hence consider the insinuations of the mechanism of the rate equation obtained.

EFFECT OF CONCENTRATION ON REACTION RATE
The aim of this experiment is to find the effect of varying the concentration of iodide ions on the rate of reaction between hydrogen peroxide and an acidified solution of potassium iodide: H2O2(aq) + 2H+(aq) + 2I⁻ → 2H2O(l) + I2(aq) The course of this

Introduction and planning
For the investigation of enzymes, I am going to conduct an experiment to see how temperature can affect the rate of reaction of enzymes by testing it with starch.
The enzyme that we are going t
The aims of this investigation are:
1. To find the rate equation of the reaction of hydrogen peroxide and iodide ions. This will be achieved by using an iodine clock method and colorimetric analysis.
2. Draw a graph of rate against concentration for each reactant (Hydrogen peroxide, potassi
The experimental laboratory procedures were divided into two categories. First the formation of phenylmagnesium bromide, and second the reaction of the phenylmagnesium bromide with the carbonyl compound. However, before any of this could be done, the refluxing apparatus for the Grignar
Enzymes are proteins that lower the activation energy needed for chemical reactions. The two main environmental factors that can affect the enzyme’s activity are temperature and pH, and each enzyme works best at a particular temperature and pH. The purpose of this enzyme kinetic expe
I generally followed most of my plan for the experiments, but to improve accuracy and reliability, I made one change. In my plan, I said that I was going to use 20cm³ of starch for each experiment. However, in my actual experiment I used 40cm³ of starch. This is because I thought I might
