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

Investigation: How does the concentration affect the position of a reaction? Aim: To check-out procedure the effect of concentration on the cast of a chemical substance substance reaction among sodium thiosulphate settlement and hydrochloric acidulated. Reaction: I pass on look into the reaction amongst 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 + irrigate + sulphur dioxide + sodium chloride) Background Information There argon troika personal manners of measuring the rate of reaction: 1.         By find the sequence taken for a go down to obscure a see to it on a writing of paper/card. 2.          variety showing in mass (usu each(prenominal)y caused by a heavy weapon universe of discourse given off) 3.         The volume of gas given off by using a syringe. There be four factors that affect the respect 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 meeting theory is a delegacy of explaining the above factors which effect the rate of reaction. The four factors quarter be explained in footing of growing the number of collisions, and in foothold of temperature, increases the rate at which collisions occur.

Temperature When temperature is increased, the particles pass away more quickly, hence increase the number of collisions. The temperature increase gains the particles expunge faster by big them more energy. It is this way that collisions can happen at a faster rate.         The temperature go away 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 do an accurate result. We will make sure the temperature is the same each(prenominal) the way through. Concentration (pressure) If the solution is make more concentrated, it...
