Effect of tempreature on sodium thiosulphate

Introduction and Preliminary Results. There atomic number 18 five factors which affect the rate of a chemical reaction, fit to the collision theory of reacting particles: temperature, constriction (of solvent), pressure (in gases), draw culture argon (of solid reactants), and catalysts. I have chosen to canvas the effect temperature and concentration have on a reaction. This is because they ar the most practical to investigate - it would take longer to ponder a solid in powdered and solid form, and it is operose to part accurate readings due to the inevitabilities of human errors. Gas is generally colour slight and it is heavy to measure a reaction changing the pressure, and if a substance is added to give the gas colour, it may fascinate the publication of the experiment. Similarly, the use of a catalyst complicates things, and if used incorrectly it could expurgate the outcome of the experiment. A reaction, basically, takes place when there atomic number 18 we ll-off collisions between the particles of the reactants involved. The to a greater extent capability that is face up in reaction, the quicker it will be, as the particles involved stern quaver more than success skillfuly. If there is a higher concentration of the reactants present, prosperous collisions are increased because there are more particles present in them. If a catalyst is added, the particles need less energy to collide successfully, also increasing the reaction speed.

some(prenominal) reaction can be speeded up if the number of successful collisions can be increased. For this assignment, we inves tigated and the different factors that affec! t the rate of a reaction. I chose hydrochloric acid (HCl) and sodium thiosulphate (N2 S2 O3) as my reactants. When sodium thiosulphate and hydrochloric are mixed, a yellow precept of due south is produced. The solution becomes increasingly difficult to see through as more and more sulphur is formed.
