  In an experiment to study how the rate of reaction varies with concentration,
  10cm³ of 0.4M sodium thiosulphate was mixed with 10cm³. Of 2M hydrochloric acid in a
  flask. The flask was placed in a white paper marked with across X.The time taken for the
  cross X become invisible when viewed from above was noted and recorded in the table
  below. The experiment was repeated three times as the temperature using the volumes in
  the table and the results recorded as shown in the table below.
  
  a) i) On the grid below, plot a graph of the volume of thiosulphate (Vertical
  axis) against time taken for the cross (X) to become invisible)
  ii) From the graph determine how long it would take for the cross to become
  invisible if the experiment was done.
