Lab Report Order Of Reaction



These reactions allowed the rate to be determined, and the rate constant to be evaluated from Censorship necessary modern society essay graph of the log R v. All of the objectives were successfully achieved American dream willy loman essay the data Lab report order of reaction. You then plot a How to write a report example samples of absorbance against concentration to give your calibration curve. If you do it the wrong way around, you How to write a report example samples just get an error message. In this experiment, numerous smaller reactions were carried out to demonstrate the chemical kinetics properties of rate laws. The Corruption essay in tamil language equation is shown below, in ionic form.

How was the rate of the reaction determined? Present your results in tabular form. Work out the rate of each reaction and add these to your results table. Conclusion 7. State the conclusion of the experiment. All other variables will be kept constant. Requirements Selection of syringes 0. Procedure 9. Using syringes measure out 10 cm3 of sodium persulphate solution and add 1 cm3 of starch solution into a dry cm3 glass beaker and place the beaker on a white piece of paper.

Fill another syringe with 10 cm3 of potassium iodine solution. Quickly add this to the sodium persulphate solution in the glass beaker and at the same time start the timer. Repeat this procedure another three times but use a different concentration of sodium persulphate each time. The concentration of sodium persulphate can be reduced by tacking less than 10 cm3 of it and making up the difference with deionised water.

How has the concentration of the sodium persulphate Na2S2O8 varied? Draw a graph to illustrate your results. State the conclusion of the experiment …………………………………………………………………………………………………… …………………………………………………………………………………………………… …………………………………………………………………………………………… Prescribed Practical Activities Learning and Teaching Scotland Draw a nine-square grid.

Choose nine of the keywords and write each one in a square, in any order. Your teacher will read a definition. If you have the matching word with the definition that your teacher has just read, cross it out. When a student has crossed out a whole line of words, he or she calls out Line!!. The line could be vertical, horizontal or diagonal. Read out your words and the meaning of each one. The teacher will continue to read the definitions until one student has crossed out all his or her squares. This student calls out: Full House!! Then the student has to read one of his or her words, asking someone in the class to give its meaning. The teacher is going to read out any definitions still remaining and is going to ask students to give his or her matching word.

Write the keywords and definitions in your notebook. Keywords Definitions Acid A chemical compound which has a sour taste and will change indicator paper to red. Exothermic The reaction supplies the energy as heat. Synthesis Two or more substances combine to form a more complex substance. Neutralization Combine and acid with a base to produce a salt and water Single A single element replaces another in a compound.

It will turn indicator paper blue. Electrolysis The separation of elements in a chemical compound by electricity Endothermic In these reactions energy has to be supplied from outside, usually as heat. Decomposition A complex substance breaks down into two or more products Oxidation Oxygen usually combines with substances to make the oxide Double Parts of two compounds switch places to form two new replacement compounds.

The error bars were based on the standard deviations calculated in the previous section. Five variations of the acid ranging from 0. Although the line of best fit is not an ideal fit with the data, especially the result for 1. From 0. Therefore, the slope of the line of best fit is This is due to the fact that higher concentrations indicate more particles in less spaces; this means that with less space to move around, these particles are more likely to collide with each other, enabling easier and faster reactions Clark.

Evaluation: The method seemed to work quite well throughout the experiment, so there were no significant errors in methodology. However, one limitation was that the process was very time consuming, since we had to ensure that there were no residues left on the probe containers and graduated cylinders after every trial. The methodology can therefore be improved if the solutions were already prepared before the actual experiment. Nonetheless, there was one major error in the process that has impacted our results. Although there were several potential systematic and random errors such as the time between the insertion of the acid and the probe and failure to dry equipment before conducting another trial, the major one is evident in the trials for 1.

The results for the other trials forming a clear positive line notwithstanding, the result for 1. This is most likely due to lapses in measurement, a systematic error — it is probable that we had misread the labels for the concentration for hydrochloric acid, or more likely had miscalculated the concentration when diluting the solution, giving us an undesired and incorrect result. In this experiment, we have diluted the acid more than desired, thus decreasing the rate of reaction than the previous trials for 1M. This error could be easily fixed, however, by simply being more careful with our calculations and the solutions we are dealing with.
