Chemistry Coursework Aim: to see how concentration affects the rate of reaction. Introduction: In this experiment we are going to be looking at how HCL (hydrochloric acid) and Sodium Thiosulphate affect the rate of a reaction. We will mix the two things together so a precipitate of sulphur will be made. There are many ways in which you could increase the speed of a reaction, for this experiment we will be changing the concentration; to see how that affects the speed of a reaction. There are many other ways to; you could increase the temperature of the substance, increasing the pressure of gas, increasing the surface area of a solid and by using a catalyst. During a reaction where the temperature is constant, the concentration of the reactants decreases and so the rate gradually slows down. For an endothermic reaction increasing the temperature may produce large increases in the rate of...
