Investigating The Effect of Concentration On The Rate Of Reaction of Sodium Thiosulphate & Hydrochloric Acid Problem I am measuring the rate of reaction (how fast a reaction takes place) of sodium thiosulphate and hydrochloric acid when affected by the concentrations being altered. In this coursework I am investigating what effect the change in acid concentration will have on the rate of reaction. According to the 'Collision theory' there are different variables that can be used to change the rate of a reaction including temperature, concentration, catalysts or increasing the surface area of solid particles. Increasing the temperature gives particles more energy, which means they will be moving around faster, and increases the chance of collisions that will break bonds. Increasing concentration increases the likelihood of collisions because there are more particles confined to a space. Using a catalyst provides an alternative reaction mechanism with lower activation energy. Activation energy is the...
