Free essay example: investing rate of reaction i am going to investigate the rate of reaction between two substances: calcium carbonate and hydrochloric acid equipment: a gas syringe, rubber bung, conical flask, stand, clamp, 25ml hydrochloric acid, 2g medium sized calcium carbonate pieces, and a stopwatch. Using a gas syringe to measure volumes of gases. This is an experiment from the practical chemistry project, developed by the nuffield foundation and the royal society of chemistry nuffield foundation the- rate-of-reaction-of-m.
Our first article, titled “microscale gas chemistry: generating gases in large syringes” appeared in the october 1996 issue of chem 13 news over the ensuing issues, we presented the preparation of a new gas each month along with a number of experiments and activities that could be done with each gas parts 2–10.
As and a-level chemistry as (7404) a-level (7405) required practical handbook version 20 extremely difficult to get sufficient variety and challenge in these experiments, and so students do well even if they have not had the opportunity to do enough eg gas syringe, collection of gas over water, decrease in.

Also so that the experiment stops by itself once the gas syringe has filled up the reasons for choosing these two independent variables are that it would be too hard to try and find a catalyst for this experiment a catalyst is a substance that increases the rate of a chemical reaction without being consumed in the reaction.
Methods experiment 1: relationship between pressure and volume at constant temperature (boyle's law) the pressure volume apparatus was set up to study the relationship between the volume of the enclosed gas sample in a 60ml syringe and the pressure it exerts at constant room temperature the plunger was used.
The examination papers will test the knowledge and understanding of chemical facts and principles and the ability to apply these to chemistry 34 competence in problem solving the coursework should not be restricted to an acquisition of information but should assess students' ability to: 341 use of the gas syringe.
