moles of HCl. Concentration.

When we did the reaction changing the concentration we changed the

concentration until we had just enough for 1 mole of magnesium to react with two

of HCl. To get a fair reaction we had to keep the amount of magnesium the same

and the temperature. We used 0.1g of magnesium.

RESULTS

Temperature

From this graph you can see that if we do increase the temperature the rate of

reaction also increases, but it does not show that if you increase the

temperature the rate of reaction doubles.

This graph shows that there is an increase in the rate of reaction as the

temperature increases. This shows a curve, mainly because our results were

inaccurate in a number of ways. This is because the concentration is changed

during the experiment because at high temperatures the acid around the magnesium

is diluted. If this experiment was accurate it would be also a curve but if you

made it into 1/time the result would be a straight line showing a clear

relationship.

Even though I changed it to 1/time it still does not show a clear relationship

because of the factors mentioned in the conclusion. Concentration

This graph shows an increase in the amount of gas given off and the speed at

which it is given off. This graph also does not show the rate increase, it just

shows how it increases with a change in concentration.

This graph shows that if you increase the concentration of the molar solution of

the acid the time in which the Mg takes to disappear becomes a lot slower. This

does not show the rate at which this happens, the graph of rate vs. conc. would

show a straight line.

This shows a straight line, thus proving that there is a relationship between

the time it takes the magnesium to disappear and the concentration of the acid.

If we take a gradient of it, it would show the rate at which the reaction was
