This includes: P2, M2, D2 questions task criterion: P2 To carry out experiments to show the effect on the rates of reactions of changes in concentration, particle size, temperature and presence of a catalyst. M2 To explain variation in rates of reaction as a function of concentration, particle size, temperature and presence of a catalyst. D2 To use data to determine orders of reaction, rate constants and rate equations. *harvard referencing included for each section* i have all assignments from level 2, 3, 3,2 available as well as a bundle of all assignments of the levels, if there is any missing dont doubt on sending me a message, share with you're friends and thanks for visiting me!!

Task 1


Concentration and the rate of reaction

Method:

- Weight 10g of marble chips on the top-pan balance
- Une a measuring cylinder to measure out 10 cm3 of 1.00 mol dm-3 hydrochloric acid.
Pour the acid into the conical flask.
(care: 1.00 mol dm-3 hydrochloric acid is an irritant.)
- Set up the following apparatus but do not add the marble chips yet




- Add the marble chips to the conical flask and quickly stopper the flask and connect
the gas syringe. Start the stopclock at the same time.
- Mesure the volume of gas (carbon dioxide) Procedur every 20 seconds.
- Do not stop the clock between readings
- Record your results in a table
- Repeat the experiment using: 20 cm3 0.50mol dm-3 hydrochloric acid, and 40 cm3
