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...

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.
The stoichiometric equation...
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...

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...
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...

The aim of this lab is to determine the order of the reaction between Propanone and aqueous Iodine with respect to Iodine.
Apparatus and Reagents
I. Eye Protection (1)
In this experiment, we alkylate sodium saccharin to N-ethylsaccharin with iodoethane in an aprotic solvent N,N dimethylformamide. Nucleophiles in this experiment will react better in an aprotic solvent. Aprotic solvents have dipoles due to its polar bonds but they do not have H atoms...
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...
For my individual investigation I plan to study the reaction between Peroxydisulphate(VI) ions and Iodide ions. To do this I plan to investigate the rate of reaction and thus find the order of reaction in respect to Peroxydisulphate ions and Iodide ions. I will study how the rate of reaction is affe...
