Chemistry Coursework: Energy released through combustion of alcohols Introduction: There are several factors that can affect Rate of Reaction. These include: * Temperature * Surface area (For solids) * Catalysts * Concentration (For liquids) For this experiment, we will be investigating concentration. Concentration affects Rate of Reaction due to Brownian motion. Brownian motion is caused by molecules of a substance colliding with another substance. In the case of certain compounds and elements, when these collisions happen, a chemical reaction can occur. In this case, we will be investigating the reaction between Sodium Thiosulphate & Hydrochloric Acid. Whether or not a reaction occurs during a collision is down to the energy of the colliding particles. If it is high enough, a reaction occurs. Temperature can affect Rate of Reaction because it affects the energy of particles. More heat will mean more energy, and so more reactions. Less heat will mean less energy, and so fewer reactions. Concentration...
