Chemical Reactions: Investigation Problem: What is the effect of the temperature of the rate of a chemical reaction? Purpose: the rate of a chemical reaction is essenti every last(predicate)y how fast the reaction is. In this investigation, we take leave alone be how temperature influences the rate of a reaction. Hypothesis: I confide that the higher the temperature (independent protean), the quick the reaction happens (dependant variable). I deal this impart happen because the higher the temperature the more the particles vibrate do them unite with other particles. Variables: The Independent variable is the temperature of the thiosulphate. The dependant variable is the clipping it takes for the reaction to happen. The controlled variables are the amount of thiosulphate and hydrochloric pane, the person winning the time, The X, the flaskfulful you use. Apparatus: Safety glasses etna burner Heat cogent evidence languor Sodium thiosulphate Hydrochloric ac id 100 ml of conelike flask chip watch 50 ml legal professionment stick piston chamber 10 ml measuring cylinder Distilled water Ice Apron Beaker Method 1. imbibe preventative equipment (apron and safety glasses) 2.Collect all materials and apparatuses 3.Set up the practical for room temperature test. 4. appear 45mls of thiosulphate in 50ml measuring cylinder.

5. mystify X of flat surface. 6.Place 5mls of acid in 10ml measuring cylinder. 7. fructify 45mls of thiosulphate in flask and tempt stopwatch ready. 8.Put 5mls of acid in same flask and skip over timer. Stop timer when you cannot see the x from a shuttles eye view. Record results, wash turn out all equipment. remove steps 4 to 8 triplet! times. 9.Set up the bunsen burner burner and put half-filled beaker of water on top of Bunsen burner. 10.Repeat steps 4 to 7. 11.Place flask in beaker and use thermometer to measure the degrees. 12.Wait till flask is 45 degrees and take out (caution may be hot) 13.Put flask on x and wash out all equipment, relieve steps 10 to 13 three times. 14.Get...If you want to get a full essay, order it on our website:
