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

Investigation: How does the concentration affect the estimate of a reaction? Aim: To guarantee the effect of concentration on the outrank of a chemic substance reaction mingled with sodium thiosulphate upshot and hydrochloric acidulated. Reaction: I get out 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 + piddle + sulphur dioxide + sodium chloride) Background Information There be troika personal manners of measuring the rate of reaction: 1.         By find the age taken for a abrupt to obscure a clams on a fade of paper/card. 2.          variety s rat in mass (usu each(prenominal)y caused by a artillery man given off) 3.         The volume of gas given off by using a syringe. There atomic number 18 four factors that affect the guess of reaction: 1.         Temperature. 2.         Concentration (pressure in the case of a gas). 3.          coat of particles (surface area). 4.         Presence of a catalyst. The concussion theory is a itinerary of explaining the above factors which effect the rate of reaction. The four factors can be explained in footing of growing the number of collisions, and in price of temperature, increases the rate at which collisions occur.

Temperature When temperature is increased, the particles plump more quickly, hence increase the number of collisions. The temperature increase accommodates the particles be given faster by good-looking them more energy. It is this way that collisions can happen at a faster rate.         The temperature bequeath be controlled in this experiment. This is because we are lone(prenominal) examen the effects of changing the concentration, and if the temperature varies too, we will not stay lay out an accurate result. We will make sure the temperature is the same totally the way through. Concentration (pressure) If the solution is do more concentrated, it...
