(c) The student repeated the experiment using the same volume of acid and the
same mass of marble chips but used smaller marble chips.

All other conditions remained the same.

The student found that the reaction with the smaller marble chips was faster to
start with but produced the same volume of gas.

Using this information, draw a line on the grid to show the results for the reaction
with the smaller marble chips.

Label this line ‘C’.
