Effect of temperature on rate of reaction
Aim:
To find out if the temperature increases the rate of reaction of two
chemicals.
Prediction:
My prediction is that the higher the temperature is the faster the
rate of the reaction will be.
Equipment:
Hot water, thermometer, flask, cold water, stopwatch, tissue paper,
paper with ‘X’ marked on it, safety glasses, measuring cylinder, large
beaker, sodium thiosulphate, hydrochloric acid.
Method:
The experiment has to be done five times for the five different
temperatures of the sodium thiosulphate. The temperatures are: 20°C,
30°C, 40°C, 50°C and 60°C
To start the experiments fill the flask with 50cm³ of sodium
thiosulphate into the large beaker. Fill the large beaker up with the
water of right temperature that is required for the experiment. Put
the thermometer into the flask with sodium thiosulphate and check the
temperature is right for the experiment. If the water is too cold, in
the large beaker pour in some more hot water or if it is too hot pour
in some cold water to reach the required temperature for the sodium
thiosulphate. Once the sodium thiosulphate is the right temperature,
take it out of the water, wipe the bottom of the flask with tissue
paper and place it onto the piece of paper with ‘X’ marked on it. Now
measure 5cm³ of hydrochloric acid in the measuring cylinder. Then pour
the hydrochloric acid into the sodium thiosulphate, at this moment
start timing with the stopwatch and keep timing until you cannot see
the ‘X’ mark through the liquid. Make sure you wear safety glasses and
handle the acid carefully.
Fair Test:
To make this investigation fair you have to make sure you use the same
concentration of hydrochloric acid for all experiments. You also have
to make sure you use the same amount of hydrochloric acid and sodium
thiosulphate for all the experiments. Also make sure you time the
experiments accurately.
Observation:
My observation was that when the temperature of the sodium
thiosulphate was higher the solution turned cloudy quicker.
Results:

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.

7.) After you have heated them to the right temperatures, pour the excess water into a dry evaporating dish. ( Be sure not to get any of the substance in your solution. )
In a 100ml beaker place 50mls of water, measure the temperature of the water and record this initial temperature onto a table. Set the timer and add one teaspoon of Ammonium Nitrate to the water, stir this continuously until the Ammonium Nitrate has dissolved.
Effect of Temperature on the Rate of Reaction between Sodium Thiosulphate and Hydrochloric Acid Investigation Chemical reactions are used in our everyday life, they literally keep us alive. They are used in food, respiration and everywhere else in the environment. A chemical reaction mainly occurs when reactants react together to produce a new product. The speed at which this reaction takes place is called the rate of reaction. The product produced has a number of particles in the solution that has formed from the reactants.
The pH of the solution would alter the rate of the reaction if it was
