SC1 Investigation: Rates of Reaction INTRODUCTION: We planned an investigation to find out the rate of reaction when we reacted sodium thiosulphate and hydrochloric acid. The rate of a reaction is defined as the speed at which the reaction takes place. Many things can affect the rate of a reaction. In this coursework I am investigating what effect the change in acid concentration will have on the rate of reaction. ANALYSIS As I mentioned before in my class work, four things affect rate of reaction. All four methods of increasing the rate of reaction can be explained in terms of increasing the number of collisions. Temperature increases the number of collisions. When the temperature is increased, the particles all move quicker. If they're moving quicker, they're going to have more collisions. Reactions only happen if the particles collide with enough energy. At a higher temperature there will be more particles colliding with enough energy to make the...
