How Fast Is Your Reaction
How fast is your reaction?
Part 1 – How temperature affect the rate of reaction
Chemical equation
Magnesium + hydrochloric acid → magnesium chloride + hydrogen
Mg + 2HCL → MgCl2 + H2

Conclusion and questions 1. What factors/variables did you keep the same in this experiment?
* We kept the same volume of hydrochloric acid (10 cm3) and the magnesium ribbon (5cm) because that way we could get a fair test experiment. We also repeated the experiment twice.
2. What does increasing the temperature do to the rate of reaction?
* In my results I found out that the rate of reaction increases as we increase the temperature. For instance at 30°C the rate of reaction is 0.006 seconds and at 60°C the rate of reaction is 0.017 seconds. This means that the lower the temperature is the faster is the reaction.
3. What conclusion can you make about the rate of this chemical reaction?
* The rate of reaction increases when the temperature increases. So doubling the temperature almost doubles the rate of reaction. This is the reason that the rate of reaction increases from 30°C, 0.009 to 60°, 0.017.
4. How does increasing the temperature affect the hydrochloric acid molecules that react with the magnesium atoms in this chemical reaction? Use particle diagrams in your answer.
* When we increase the temperature the particles start to collide and bump to each other. They have more energy and that affects the rate of reaction.
5. Using the chemical equation, write down the following : a) The reactants b) The products c) The state of matter of all the reactants and products d) If the chemical reaction is reversible or irreversible. a) And b) Magnesium + hydrochloric acid → magnesium chloride + hydrogen.
Reactants products
c) Mg – solid HCL –
