These reactions only happen if the reacting molecules collide properly. This module provides students with the background knowledge and understanding of the ways in which signals are captured from sensors, then amplified, and then fed into a data acquisition system.

Practical sessions allow students to demonstrate their progress on a weekly basis through idea generation, peer presentations, elevator pitches and formal presentations.

You will undertake advanced topics and will cement your specialist chemical engineering knowledge through an individual project, which will have real, positive impact on businesses and society. Use smooth 'best curves' for as many of the points as possible, though some parts of the graph might be linear, watch out for the 'scatter' - the experiment is not that easy to get good results.

As a result, students will gain an appreciation of designing simple engineering structures to achieve the required strength and stiffness for a wide range of manufactured products. Graphs All of the graphs that I drew for this investigation show a negative correlation.

Completing this module will enable students to recognise the limitations of numerical modelling and simulations. Conclusion In my investigation, my data and my graphs proved that my hypothesis was correct.

They will also gain a deep understanding of the principles of process evaluation with regard to sustainability as represented by safety, health and environmental and economic impact.

The size of the error bars is quite small so I think I can say that my data is quite accurate except for the 2M result which is quite a long error bar. Also many other variables affect the collision rate to increase such as Catalysts and temperature etc. This shows that my data is quite accurate.

Classes are supported by weekly conversation lessons in small groups to promote oral fluency. Also safety was equally important to the investigation.

The results are initially processed into graphical form 'graphing' for several reasons for both the analysis and evaluating the experimental Around a quarter of the people in the EU speak German as their native language.

Example of the theory is the factors will increase the molecules inside the chemical and it will eventually increase the rate of reaction.

Where as when the STS was at 40ml the average time was 32 seconds which shows a very big relationship between the amount of STS and the time taken. Evaluation All of my results were accurate and fitted the pattern of results. And supports my conclusion. The module is based on exploration and discovery and evaluated through coursework alone.

My experiment was carried out very safely. - Rates of Reaction BACKGROUND INFORMATION What affects the rate of reaction.

1) The surface area of the magnesium. 2) The temperature of the reaction. 3) Concentration of the hydrochloric acid. 4) Presence of a catalyst. In the experiment we use hydrochloric acid which reacts with the magnesium to form magnesium chloride.

This is an experiment to investigate into the rate of reaction between sodium thiosulfate (Na2S2O3) and dilute hydrochloric acid (HCl).

The formula for this reaction is: Na2S2O3 (aq) + 2HCl (aq) 2NaCl (aq) + S(s) + SO2 (g) + H2O (l). For the hydrochloric acid - sodium thiosulphate reaction you can plot either (i) reaction time, or (ii) 1/time versus a concentration or temperature (1/time = relative rate of reaction).
