The Effect of Temperature on the Rate of Reaction
Aim
The aim for this investigation is to carry out an experiment which I
will be able to examine and measure the way temperature effects the
rate of reaction in a number on conditions. The substances which will
be used in my experiment to find how temperature effect the rate of
reaction are Hydrochloric acid and Sodium thiosulphite they are going
to be used at a range of different temperatures to maintain this, they
are going to be placed in water baths programmed to get the substances
to the right temperature before used in the experiment.
Rates of reaction can be altered by the following:
* Surface Area
* Catalyst
* Concentration
* Temperature
The theme of this coursework is "temperature" and how it effects the
rate of reaction that will be the factor which this coursework will
revolve around investigating.
Prediction
I predict that when the substances are heated, the rate of the
reaction will rises conversely, if they are cooled, the reaction slows
down. In order to react, the particles in the substances must collide
with each other. The rate of reaction simply depends on how often and
how hard the reacting particles collide. I predict that the particles
have to collide hard enough to produce a reaction between the
Hydrochloric Acid and the Sodium Thiosulphite and the heat gives them
more energy to move around and so increases the chances of a
collision. Also, when particles do collide, they are more likely to
react, rather than just bounce off each other, if they are moving
faster. Cooling has the opposite effects, so the higher the
temperature the faster I predict that the hydrochloric acid and the
Sodium Thiosulphite are going to react which. The two chemicals which
will be used in this experiment are both clear solutions, so i think
when the reaction occurs it will turn cloudy or it might bubble these
In a substance the rate of reaction will be quicker if it has a large
It is important however to note that the NH4 and K ions are still in
the large beaker pour in some more hot water or if it is too hot pour
In this experiment there five different phases and in each a different factor of the Collision Theory was tested. The first phase was called, Nature of the Reactants and it had three parts to it. In the first part of it which was steps 1-4, 5 pieces of mossy zinc were put into 3ml of 2M H_2 〖SO〗_4 and during this time bubbles were produced. After a few minutes the zinc was removed from the acid and it was now clean zinc.
Investigation looking At the Speed of Reactions Introduction The aim of this experiment is to find out how a variable can affect the results from a scenario set up in scientific environment. The experiment is to see how a certain variable will affect the amount of Gas produced from a Calcium Carbonate and Hydrochloric Acid Reaction. The Science Calcium Carbonate is a generally white or colourless mineral that is translucent.
The Effect of Temperature on the Rate of a Reaction Aim and Hypothesis The investigation that we have chosen to do is how the effect of temperature affects the rate of reaction of hydrogen peroxide to water and oxygen using the enzyme catalase. I predict that the higher the temperature the faster the rate of reaction will be and the more oxygen there will be given off. I've based this prediction on kinetic theory (every 10 degree rise in temperature the rate of reaction doubles.) This is because the substrate will lock on twice as fast, as it is travelling twice as fast.

The Effect of Temperature on The Rate Of Reaction Between Magnesium And Hydrochloric Acid Planning I'm planning on investigating how temperature effects the reaction between magnesium and hydrochloric acid, the experiment will show whether the reaction will speed up or slow down with the change in temperature. Temperatures will range from room temp up until 70 degrees. The investigation will be a fair test because all quantities will remain the same for each test, each test will use the same amounts of hydrochloric acid and same size of magnesium, also the concentration of the acid will also not be changed.

In this lab the group studied the effect of temperature on rate of chemical reaction
The problem of this lab is, “What factors affect the rate of chemical reactions?” The hypothesis is, “Temperature, concentration, surface area, and catalysts affect the rate of chemical
The pH of the solution would alter the rate of the reaction if it was

The Effect of Temperature on the Rate of Reaction Between Hydrochloric Acid and Calcium Carbonate
Looking at the table of results above and the graph, it is shown that the higher the temperature got, the shorter the reaction time. The obtained results have been plotted on a line graph of the temperature of hydrochloric acid (y-axis) against reaction time (x-axis). This line graph in fig.2 also clearly shows that as the temperature increases, so does the speed of the reaction, shown by a reduction in the time taken. This corroborates the collision theory, where as the temperature of particles increase, the particles gain more kinetic energy and react with each other upon collision. This is shown as to happen in the hydrochloric acid, where the hydrochloric acid particles collide more with the particles of the magnesium ribbon as the temperature was increased. The above graph shows a gradual sloping curve, which gets steeper at higher temperatures. This shows that the reaction will reach a peak rate of activity as the gaps between the temperature and reaction times continue to decrease. The experiment fulfills the aim and clearly shows that as the temperature of a reaction is increased so does it’s rate of reaction, proving the hypothesis to be correct.
My aim in this piece of work is to see the effect of temperature on the rate of a reaction in a solution of hydrochloric acid containing sodium thiosulphate.
