Room Temperature Lab Report
In graph 1.2 it can be seen that the relationship between temperature and the reciprocal of time is very close to being directly proportional. This shows us that as the temperature increases, the rate of reaction decreases. For it to be directly proportional it must pass through the coordinates (0,0), however the graph passes though (0,0.069) which is very close. It may be that the relationship is directly proportional and that the small difference is due to systematic errors in the practical.
A random error is an error in which its effect on measurements vary in each trial. Hence this type of error has an effect on the precision of data. Precision is how close together a set of measurements are regardless of how far away they are from the true value. …show more content…
Even during the reaction, it would be decreasing in temperature this mean an average temperature would have to be determined by measuring the temperature before and after the reaction. However, the time taken to get the solution out the water bath and complete the procedure was different each time meaning some would’ve lost more heat then others, hence a different temperature was used for each trial, as can be seen in table 1.2. This would affect the rate of reaction and have a random effect, effecting
