Introduction

Does The Temperature Of Hydrochloric Acid Affect The Rate Of The Chemical Reaction Between Hydrolic Acid And Magnesium? Analysis Temperature of hydrochloric acid 0c Time taken for magnesium to react Seconds 14 141 20 80 27 73 39 55 50 52 60 51 Hydrochloric acid + magnesium magnesium chloride + hydrogen 2 Hcl MG MGCL2 H2 From my results I can conclude that the hotter the hydrochloric acid the quicker the reaction time between the acid and magnesium. The results show certain patterns and trends, for example the test where the acid was at 14 C the magnesium took 141 seconds to react and 27 C test took 73 seconds to react. This shows roughly that if you double the temperature then the reaction time will half. The reason that when the hydrochloric acid was at 14 C the reaction time for all the magnesium to react was 141 seconds was because the molecules of the acid and magnesium didn't have a lot of kinetic energy, so there was not much movement therefore there were not many successful collisions. ...read more.

Middle

The conclusion I have made supports my prediction by saying that the hotter the acid the quicker the rate of reaction. We still don't know however if there is a point below 14 C if no reaction occurs because in the test we did, the lowest temperature we did was 14 C Also we don't know if there is a point above 60 C if the reaction cannot become quicker because the highest temperature we did was 60 C. Evaluation For this experiment my prediction was correct. My results have proven that the hotter the acid the faster the rate of reaction. Our results were good because we only had one anomaly. The anomaly was at 27 C. All in all the experiment was successful and we proved our predictions right. There was however one anomaly and this could have been due to a number of reasons. If I did the experiment again I would only change a couple of things. ...read more.

Conclusion

I also cannot make a firm conclusion below 14C for instance 5 C this might be the point where no reaction occurs at all so even if the acid were at 1 C there would be no difference in the time of reaction. All reactions go faster at a higher temperature. Temperature has a very noticeable effect the rate of many reactions is doubled by a temperature rise of just 10 C. If I did the experiment again I would initiate my improvements and also do a test showing higher and lower temperatures e.g. To find out if there is a temperature below 14 C where by the reaction doesn't occur for example -20 C, I would use a freezer to find out if this is true. To see if there is a temperature above 60 C where the reaction doesn't take place I would use acid at 100 C to test this by using a water bath. I would do both these implementing my experiment changes ...read more.

    This is because by the 30-second mark there would be less hydrochloric acid and calcium carbonate particles available to collide with each other as some of these particles have already reacted to form calcium chloride, water and carbon dioxide gas.

  1. How does temperature affect the rate of reaction between Magnesium and Hydrochloric acid.

    If the particles collide head on (a direct collision) then the impact is greater so the collision is more effective. However if the molecules collide at a different angle (an indirect collision), they may simply bounce off each other so the collision is not effective.

    accurate set of result, because having to keep timing and recording result include a high percentage of experimental error. Acid volume measurement is important, and measuring cylinder was not accurate enough, so I decided to use burette. Mg has to be an excess to not affect the rate, and the more percentage of excess, the less error it would be.

Temperature- the temperature adds energy to the reaction an affects how quickly the particles move. By doing this temperature affects the number of affective collisions Light intensity- the light

  1. How does temperature affect the rate of a chemical reaction?

    Put more simply - a higher concentration has more particles in the same volume thus increasing the number of collisions per second leading to an increase in the rate of reaction. 3. Temperature - When the temperature is increased the rate of reaction is increased.

  2. Factors That Affect the Rate of a Chemical Reaction.

    I predict that the rate of reaction should change as I add catalysts. Catalysts are substances that can influence the reaction by two ways; either to increase, or decrease, the rate of reaction. It can increase it either by weakening the chemical bonds that are needed to be broken,
