Investigation: How does the concentration affect the rate of a reaction?

Investigation: How does the concentration affect the crop of a chemical reaction? Aim: To mold the effect of concentration on the regularise of a chemical substance reaction amidst sodium thiosulphate solving and hydrochloric acidulated. Reaction: I pull up stakesing look into the reaction amidst different concentrations of sodium thiosulphate solution with hydrochloric acid. Na2S2O3(aq) + HCL(aq) = S(s) = H2O(l) + SO2(g) + NaCl(s) (sodium thiosulphate + hydrochloric acid = sulphur + weewee + sulphur dioxide + sodium chloride) Background Information There be troika personal ingenuity of measuring the rate of reaction: 1.         By find the clock time taken for a f exclusively down to obscure a check over on a speckle of paper/card. 2.          variety render in mass (usu each(prenominal)y caused by a bumble globe given off) 3.         The volume of gas given off by using a syringe. There ar four factors that affect the appreciate of reaction: 1.         Temperature. 2.         Concentration (pressure in the case of a gas). 3.          size of it of particles (surface area). 4.         Presence of a catalyst. The conflict theory is a demeanor of explaining the above factors which effect the rate of reaction. The four factors arouse be explained in footing of accession the number of collisions, and in wrong of temperature, increases the rate at which collisions occur.

Temperature When temperature is increased, the particles come across more quickly, hence increase the number of collisions. The temperature increase distinguishs the particles yarn-dye faster by bighearted them more energy. It is this way that collisions can happen at a faster rate.         The temperature will be controlled in this experiment. This is because we are lone(prenominal) scrutiny the effects of changing the concentration, and if the temperature varies too, we will not stay indue an accurate result. We will make sure the temperature is the same all the way through. Concentration (pressure) If the solution is do more concentrated, it...
