Aim:
The aim of the experiment is to investigate the factors affecting the rate of reaction between HNO3 and CaCO3, and why it affects the rate of reaction. ...
2) Surface Area
3) Pressure
4) Concentration
5) Catalyst provides a surface
Hypothesis
I believe that by increasing the temperature in controlled amounts will increase the rate of reaction between CaCO3 and HNO3. ... This results in more reactions, and thus a higher reaction rate is achieved.
If this theory is correct then the graph of results will look something like the following:
Outline
This experiment will test whether temperature affects the rate of reaction. ... This experiment will be repeated in different temperatures to observe the interaction of temperature with the reaction.
The rate of reaction will be measured by measuring the amount of CO2 produced every ½ minute for 5 minutes. ... The measuring cylinder should be used to measure the volume of CO2 given off by the reaction between CaCO3 and HNO3, and the volume of gas should be taken very 30 seconds for a total period of 5 minutes. ...
Average Rate of Reaction for each Temperature:
Start Temperature (OC) Finish Temperature (OC) Rate of Reaction (CM3/MIN)
10 10 6.
