Year 11 Chemistry Coursework: What Affects the Rate of Reaction? In this investigation I am trying to find out how to change the rate of reaction between sodium thiosulphate and hydrochloric acid. Background Information In this investigation I am investigating with this reaction below: Sodium thiosulphate + Hydrochloric acid à Sodium chloride + Water + Sulphur dioxide + Sulphur Na[2]S[2]O[3(aq) ]+ 2HCl[(aq) ]à 2NaCl[(aq)] + H[2]O[(l) ] + SO[2] + S[(s)] In any chemical reactions, there are number of factors that can affect the rate of reaction, these are listed below. Temperature The atmospheric temperature can affect the temperature of the mixture in a chemical reaction, as the temperature increases, the particles inside the mixture has more kinetic energy to move, therefore, the particles will have more successful collisions with their reactants, thus increasing the rate of reaction (figure 1). Figure 1 (left) - particles vibrates more in higher...
