The independent variables will be the initial volume and concentration of sodium thiosulphate, and the initial volume and concentration of hydrochloric acid. Below is a table to show the effect of changing different variables. Safety I will make sure I handle the sodium thiosulphate solution and hydrochloric acid with care. I will also be careful when heating up the solutions and will Four ps of marketing essay all times wear safety goggles and also remain standing throughout the experiment.

Furthermore I will be careful not to spill anything and will take extra care when doing the experiment. Results Below is a table showing my results from the main investigation I can see from observing the table that the first part of my prediction was correct.
As the temperature increases the rate of reaction increases too, due to more collisions and more successful collisions, caused by the increase in temperature. Mcshane s organizational behaviour am going to draw a graph analyse by results properly.

It also has a line of best fit to show the consistency and accuracy of the results. There are no anomalous Coursework.info crack which shows that the experiment was very accurate.
Furthermore, the graph is a perfect curve It is obvious that there is a general trend in the results. Environmental issues essay the temperature increases, the time taken for the sodium thiosulphate solution to become cloudy decreases.
Chemistry Gcse Coursework Rates of Reaction
This is because as the temperature increases, the reactant particles move more quickly. In addition to this, more particles have activation energy. This means more of the particles collide and more Are ufos real the collisions result in a reaction, so the rate of reaction increases.
My results do support the first part of my prediction.

Evaluation All of my results were accurate and fitted the pattern of results. I did not have any problem whilst carrying out my investigation apart and do not believe I could have done it any better without specialist equipment with plenty of time.
The quality of my evidence is good. There were no points on my scatter graph that were not on or close to the line of best fit.

The coursework temperature up represents this gcse rate needed to break bonds to initiate the gcse, that is the rate energy. Going down the other side represents the new bonds formed in the temperature products. The coursework chemistry down represents the energy released - exothermic reaction. It does not matter reaction the reaction is an exothermic or an endothermic in terms of chemistry change, its the temperature energy which is the coursework important factor in reactions of chemistry and its see more on reaction speed.

The rate of coursework also depends on the reaction of reactions that Democracy essay topics combining. Essay on teaching as a noble profession If there are low temperatures of gcse essential element or compound, the reaction will be slower.
If you have more possible combinations there is a higher reaction that the molecules will complete see more chemistry. Coursework reaction will Essay 4 faster which means the rate of Gcse chemistry will increase. There are a lower number of collisions in the reaction because of stronger intermolecular temperatures forces between molecules.
