Effect Of Temperature,Rate Of Chemical Reactions

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 each(prenominal)y how fast the reaction is. In this investigation, we withdraw from alone be how temperature influences the rate of a reaction. Hypothesis: I confide that the higher the temperature (independent covariant), the quick the reaction happens (dependant variable). I debate this impart happen because the higher the temperature the more the particles vibrate making 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 window glass, the person taking the time, The X, the flaskfulful you use. Apparatus: Safety glasses etna burner Heat trial impression languor Sodium thiosulphate Hyd rochloric acid 100 ml of conic flask chip watch 50 ml measuring stick piston chamber 10 ml measuring cylinder Distilled water Ice Apron Beaker Method 1. imbibe natural rubber equipment (apron and safety glasses) 2.Collect all materials and apparatuses 3.Set up the practical for room temperature test. 4. personate 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 feces stopwatch ready. 8.Put 5mls of acid in same flask and put down timer. Stop timer when you cannot see the x from a t inkers dams eye view. Record results, wash ! bug out all equipment. remove steps 4 to 8 one-third 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 mensuration 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: BestEssayCheap.com
