GCSE Science/Rates of reaction coursework

#

Now you can increase the concentration of the other solution to produce an increase in the rate of the reaction.

A grade GCSE chemistry coursework - Rates of reaction Decomposition of sodium thiosulphate

#

In my opinion if water is mixed with less concentrated sodium thiosulphate, the reactants becomes very dilute causing the reaction to be slow.

#

Biology Coursework Enzymes

#

I managed to get most of the timings accurate.

#

Rates of Reactions

#

Adding extra catalyst will make absolutely no coursewori. A grade GCSE chemistry courseworkRates of reactionDecomposition of sodium thiosulphate, introduction, method, safety, results, discussion.

Chemistry Gcse Coursework Rates Of Reaction

#

You can help make it better.

#

#

Then I had to decrease the amount of sodium thiosulphate by 30ml and it took 1.

#

#

Briefly explain how the method can be used to measure the speed - the results of the first few minutes is usually the most crucial - you can discuss briefly other methods, but perhaps better in evaluation as a means of further british essay example. I biology rate of reaction coursework carried out the amount of reactants correctly and accurately.

Sodium thiosulphate Water 50 0 40 10 30 20 20 30 10 40 3. Thanks so much for this!

#

Chemistry Rates of Reaction Coursework The system consists of a light beam emitter and sensor connected to computer and the reaction vessel is placed between the emitter and sensor.

#

#

Increasing temperature means the molecules move faster. A Wikibookian has nominated this page for cleanup.

#

#

I will also be careful when heating up the solutions and will at all times wear safety goggles and also remain standing throughout the experiment.

#

#

So making the particles smaller means that there are more of them to collide with each other meaning that there will be more collisions and a faster reaction.

#

#

The quantity of the reactants.

#

#

Rates of reaction by pierstaylor - US Teacher The time for the cross to disappear was very exceptionally high.

#

#

How good are date results then? If you are looking at changing the reaction temperature, its not easy to accurately vary and control the temperature of the reactants without a thermostated water bath to hold the reaction flask in.

#

#

If one of the reactants is a solid, the surface area of the solid will affect how fast the reaction goes. Rates of reaction between Magnesium and HCl

#

#

Apparatus The equipment which I will use are: So making the particles smaller means that there are more of them to collide with each other meaning that ciursework will be more collisions and a faster reaction.

#

#

Now you can increase the concentration of the other solution to produce an increase in the rate of the reaction.

#

From the graph you can then describe in words what the results mean, always refer to the graph lines and gradients directly - don't make vague comments.

#

In the main investigation I will see if this applies to my results.

#

Introduction Introduction This is an investigation about the decomposition of sodium thiosulphate.

#

Looking at my results I can see that the higher the concentration of sodium the faster the rate of reaction.

#

In addition to this, more particles have activation energy.

#

So this is collision theory again.

#

The range of my results were also suitable to make good observations and conclusions.

#

An increase in temperature rahe in an increase in the kinetic energy of the particles, so more will have the required activation energy for successful collisions.

From the graph you can then describe in words what the results mean, always refer to the graph lines and gradients directly - don't make vague comments. In my graph I can see that there was one result that was anomalous. Views Read Edit View history. A grade GCSE chemistry coursework. Sulphur forms a colloidal precipitate which gives the solution a cloudy yellow appearance.

Two catalyst reactants are used in the experiment, thiosulfate and starch, to dictate the time of reactions My predictions match my results because I predicted that the higher the concentration of sodium thiosulphate the faster the rate of reaction. I worked it out by using my head.

Then go to Chemistry 1 and Great article which really helped me with my experiment. I used all the equipment I was supposed to. Chemistry Rates of Reaction Coursework For the hydrochloric acid - sodium thiosulphate reaction think about the precipitate, observing it etc. It is more likely to occur in areas, where there is more pollution.

My graph shows a curve going down from 10ml to 50ml. So the larger the surface area of the solid, the faster the reaction will be. Also, is that all you need to talk about for the preliminary results.

I believe I carried out my investigation very well. Retrieved from " https: In other languages Add links. An essential element of chemistry is finding reaction rates. Discuss possible sources of error which might lead to inconsistent results i. For different the acid concentrations you can do a 2nd and more advanced graphical analysis of the limestone results.

Changing the pressure In this particular investigation I am going to find out how heat affects the rate of reaction in the reaction of sodium thiosulphate with hydrochloric acid. Also this subject is a common coursework for Chemistry , Apparatus The equipment which I will use are: The time it took previously doubled not twice but more than four times.
