Gcse chemistry coursework rates of reaction evaluation

gcse chemistry coursework rates of reaction evaluation But you can use and extend these 'brain stormed' ideas to most rates of reaction coursework assignments eg the magnesium/zinc + acid reaction, you can investigate acid concentration and amount of metal and the zinc reaction is catalysed by copper and other ions in the acid).

Rates of reaction chemistry coursework introduction 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. The reason why the temperature increases the rate of reaction can be explained by the collision theory as mentioned in the introduction, one way of increasing the rate of reaction is to increase the number of very energetic particles. Reaction rates are explained by the collision theory the collision theory is explained by the rate of reaction [tags: gcse chemistry coursework investigation] research papers 2994 words gcse chemistry coursework investigation] free essays 2369 words (68 pages) rates of reaction essay evaluation i think my results were very.

- reaction rates the 4 factors that control the rate of a reaction are: concentration temperature surface area (substances size) catalyst concentration in this experiment i am going to find out how the rate of reaction between sodium thiosulphate and hydrochloric acid is affected by changing the concentration. The way they increase the rate of reaction is by increasing the probability of a collision if the concentration of a solution is increased then there are more reacting particles in the same volume and so there is a greater chance of them colliding with each other. If you are doing something like the hydrochloric acid - sodium thiosulphate reaction, your reaction time measures the formation of a fixed amount of sulphur per 'time' so the rate is 'x amount of sulphur per time', which means the speed or rate is proportional to 1/time, then plot this 1/time against the concentration of the acid. Chemistry gcse coursework rates of reaction 1 january 2017 chemistry investigating how the concentration of sodium-thiosulphate (sts) and hydrochloric acid (hcl) affects the rate of reaction in the experiment also many other variables affect the collision rate to increase such as catalysts and temperature etc evaluation in.

It is easy to see that in the graph labelled t+t there is a large increase in the number of particles with energy greater than the activation energy therefore, when they collide, they will react this results in an increase in the rate of reaction evaluation overall i feel this experiment went well. Gcse chemistry coursework: investigating the rate of a reaction your task is to plan, and carry out, an experiment to discover how to change the rate the reaction between sodium thiosulphate solution and dilute hydrochloric acid. Gcse chemistry coursework : rates of reaction chemistry table of contents table of contents 1 strand sa 2 the science 2 variables 2 temperature 2 concentration 2 my prediction 3 strand sb 3 risk assessment 3 preliminary equipment 4 preliminary method 6 strand c 7 preliminary data 7 main method 8 main results 9 strand ea 9 problems encountered when collecting data 9 alternate methods 10.

Note that if the temperature of a rates experiment was too low compared to all the other experiments, the 'double error' would occur again, but this time the measured gas volume and the calculated speed/rate of reaction would be lower than expected.
