Rates of Reaction Experiment :: Papers

Rates of Reaction Experiment Rate of answer means the regularize of formation of a product/disappearance of a reactant, this is useful because we tail assembly succession the different concentrations reacting with the acid, and give each of them a rate, based on the formula rate = 1/time. Rate of reaction is what we use to measure how quickly a reaction takes to reach a real point in the reaction in this case it is when it gets to certain cloudiness. In this investigation, we will need to measure the time of the reaction, so we can make a rate for it, to do this we use the formula, - rate = 1/time * 1000, we use the *1000 so that it is a manageable add to plot on a graph if necessary. It is mainly metric in time, as this is the only means possible to us however you must(prenominal) be careful because as heat is a catalyst, it strongly affects the rate as you will see in the results, so we have to search and keep it the same throughout the exper iment. The reaction we are studying is very(prenominal) easy to monitor and time. All of the products in the solution dissolve into it (sodium chloride, due south dioxide and water), apart from sulphur, which makes the solution go cloudy, and forms a precipitate. This can be pen down as s-1for example 15.7 s-1means 15.7 per second is the rate of the reaction. The rate is generally measured by selecting a certain amount of two substances, and purpose a suitable way of judging when the reaction has finished, the reaction is thence timed, and when you have a time, you put it into the formula rate = 1/time *1000.This is the only method available to us, because it can not be make any other way for this experiment, but others may be measured in different ways, i.e. mass loss, or amount of gas evolved could be measured. The Equations for this experiment are Sodium thiosulphate + Hydrochloric acid Sodium chloride + sulphur +
