Question 21

A student investigated the rate of reaction between magnesium ribbon and dilute hydrochloric acid.

The volume of hydrogen gas produced was measured every 10 seconds. The results are shown in the table below.

Time in seconds0102030405060
Volume of hydrogen gas in cm3\text{cm}^3cm30254151565858

A graph grid with 'Time in seconds' on the horizontal x-axis (ranging from 0 to 70, with major grid lines every 10 seconds) and 'Volume of gas in \text{cm}^3' on the vertical y-axis (ranging from 0 to 60, with major grid lines every 10 \text{cm}^3).

On the grid, plot the results shown in the table.

Draw a curve of best fit.
