(b) The experiment is repeated using granules of zinc in excess added to the
same volume of dilute sulfuric acid, with the same concentration.
The reaction is completed in less time, but the same volume of gas is
produced. Fig. 6.2 shows the results of both experiments.
experiment 2 (zinc granules)
volume/cm
experiment 1 (lumps of zinc)
time/s
Fig.1.2
(1) State why the reaction is faster when zinc granules are used.
(1) Explain why both reactions produced the same amount of gas.
