1. A group of students investigated the rate of reaction between magnesium
ribbon and hydrochloric acid. They measured the volume of hydrogen gas
produced over time using the apparatus shown in Figure 1.
Time (s) Volume of H₂ (cm³) with 1M HCl Volume of H₂ (cm³) with 2M HCl
0 0 0
10 8 18
20 15 32
30 21 42

50 30 50
60 32 50
The students varied the concentration of hydrochloric acid while keeping all other
factors constant. They recorded their results in the table below:
(a) On the grid provided, plot the results for both concentrations of
hydrochloric acid. Draw smooth curve through the points. (3 marks)

(b) Calculate the initial rate of reaction for the 2M HCl experiment in cm³/s. Show
your working.
(2 marks)
(c) Explain, in terms of collision theory, why the reaction with 2M HCl is faster
than the reaction with 1M HCl.
(1 mark)
