How does temperate affect the rate of reaction between sodium thiosulphate and hydrochloric acid?
Aim
The aim of this investigation was to find out what affects the reaction of sodium thiosulphate (Na2S2O3 ) and Hydrochloric acid (HCl), and to evaluate any models that seek to explain the behaviour of the reactants. In this particular investigation, temperature was studied.
Hypothesis
It is predicted that when the temperature is increased by 10º C, the rate of reaction will also double. As the temperature increases more particles will posses the activation energy (Ea) needed, (the minimum energy required before a reaction can occur), for the reaction to occur. A successful collision between two molecules can only occur if each of th
