Title: Iodine time reply

Purpose: To observe factors that affects the lay of a reaction.

Hypothesis: 1. The reaction identify will plus if the concentration increases.
2. The reaction rate will increase if the temperature increases.
3. If the reactants control weak bonds, the reaction time will decrease, thereby change magnitude the reaction rate.
4. If the catalyst is added, the reaction time will decrease, so the reaction rate will increase.

Materials:
confer to the Iodine Clock Reaction handout. In the part 2 lab -- the military unit of temperature

Procedure: portion 1 -- forcefulness of stringency.
Procedure: Part 2 -- Effect of Temperature.
Procedure: Part 3 -- Effect of Nature of the Reactants
Procedure: Part 4 -- Effect of a Catalyst.
Please refer to the Iodine Clock Reaction handout.

Results:
Refer to the info table and the graph sheets (Temperature vs. Time & Concentration vs. Time).

Calculations: Refer to the handout sheet.

Conclusion:

The Iodine Clock Reaction lab is to observe the factors that can affect the rate of the reaction, much(prenominal) as the concentration, temperature, the reputation of the reactants and the catalyst.

According to the data the purpose was achieved.



In the study of the upshot of concentration on the rate of a reaction, it was found that when increasing the concentration of a reactant, the rate also increases. This was seen in both the class average data as well as individual data. And the results were shown as a best fit line graph except for any(prenominal) minor errors that due to the inaccurate measurements. In the experiment of the effect of temperature on the rate of a reaction, we can see that temperature is change magnitude so is the rate, its also shown as a liquid curve line on the graphing paper but relieve have some little errors.

In the effect of nature of the reactants test, it showed us the time it took for the reaction to completely occur was minute when place FeSO4...If you want to get a full essay, prescribe it on our website: Orderessay
