The topics included in this Starter for ten activity are: collision theory, sketching Maxwell-Boltzmann and the importance of Maxwell-Boltzmann. 

Example questions

This question is all about the reaction between zinc metal and hydrochloric acid to produce zinc chloride and hydrogen gas.

1. Write a balanced symbol equation for the reaction that occurs.
2. The reaction flasks below show the same reaction but under different conditions. The acid is in excess in all five flasks.

1. In which flask is the reaction rate the slowest?
2. The graph below shows how the volume of hydrogen given off changed with time for the reaction that occurred in flask A. Sketch on the same set of axes, the curves you would expect to get if you repeated the measurements for flasks B, C, D and E.
