How does the change in temperature affect the rate of reaction? Essay

* Guiding Question How does the change in temperature meet the rate of reaction?* Objectives The objective of this experiment is to see how temperature affects reaction rates.* possible action We think that temperature increases the rate of reaction because the increase in temperature increases the energy of the particles and accordingly overcomes faster the activation energy.* Variables1. Independent Temperature (C)2. Dependents Time (s) and rate of reaction (s -1)3. harbour Volume (ml) and concentration (M) of HCl and Na2S2O3.* Procedurea) Transfer 50 ml 0.0400 M sodium thiosulfate tooth root into a 50 ml flask.b) With a sucker make a black cross in a radical and put it below the flask.c) At room temperature quickly pour 5ml HCl of a 2M solutiond) Measure the time needed for the black cross to disappeared.e) plagiarize this procedure and indeed place the flask in a calorific plate using a thermometer and vary the temperature to 30 C, 40 C, 50 C and 60 C.f) Repeat the exp eriment twice for each temperature and recover the average.* Materialsi. 2 measuring cylinder (50 ml)ii. Thermometer 10 C 110 Ciii. Chronometeriv. 2 flasks (250 mL)v. 60 ml of a 2M solution of HClvi. 600 ml of a 0.04 M solution of Na2S2O3* ObservationSodium Thiosulfate ions (0.04 M) with different temperatures CmL HCL (2M)* ConclusionLooking at the graph and table, we fag see that as the temperature increase, then the rate of reaction increases too. This can be defined and formulate by the collision model. Particles can only react when they collide. If the substance is heat, then the particles move faster because they would started to bounce around the space faster because they withstand receive more energy. So they would bounce around more therefrom they are more likely to collide.Some problems during the experiment were that we just have one hot plate so we loose time waiting for the other team to finish with their results. It was complicated because we couldnt have replete space to record everything that was happening because there were two groups per table.A solution to this problem is that for that specific part when we need the hot plates, we can address the data obtained in the whole table members. So we can move the experiment at a faster rate so we can start doing more researches for the conclusion. And in this way the observations would have been more true statement for both groups.
