Our assignment was to produce a piece of coursework investigating the rates of reaction, and the effect different changes have on them.
The rate of reaction is the speed of a chemical reactions, usually used in terms of the concentrations of reactant consumed in a given time.
What could affect the rate of a reaction
* Temperature
* Concentration (of solution)
* Surface are (of solid reactants),
* And Catalyst
I have chosen to investigate the effect the concentration will have on the rate of reaction.
This is because it is the easiest and the most practical to investigate -
*it would take longer to prepare a solid in powdered and unpowdered form,
*it is difficult to get accurate readings due to the probability of human errors,
*the use of a catalyst complicates things, and if used incorrectly could affect the end results.
