Because this shows a straight line we can say that it is a second order

reaction.

This graph shows a nearly straight line which shows that there is a

relationship between the temperature and the rate of reaction, as the

gradient shows the rate of reaction. If you look at this graph it comes out to

show that if you increase the temperature by 100C the gradient of the line is

doubled. This shows that rate ? temp.

This graph shows that if you increase the molar concentration of the acid, you

will increase the rate of reaction. From this you can see from the gradient,

that if you double the molar concentration of the acid the rate of reaction will

double because the gradient is a way of showing the rate of reaction.

If you compare the quantitative observations to see which the faster reaction

is you can see that after 10 seconds: Temp.2102030

4050 Amount of H2 produced after 10s7.5162554

57 83

Even though there is a greater increase in the amount of H2 given off in each

of the different reactions you can see that there is a change in the amount

given off, but between the temperatures 30 and 400C there is not much of a

change, this could be because of our human error, there should be a big change

in the amount given off. Molar conc.0.511.52 Amount of H2

produced after 10s6256090 This table shows a nice

spread of results throughout the range of concentration. It clearly shows that

the reaction is at different stages so is therefore producing different amounts

of H2. This shows also that the reaction is affected by the concentration of

the acid.

CONCLUSIONS

I conclude that if you increase the temperature by 10oC the rate of reaction

would double, this is because of using the kinetic theory and the probability

theory. Even though our results did not accurately prove this, the theory that
