To investigate the factors which affect the rate of reaction between marble chips and hydrochloric acid, with one in specific detail. An investigation into how surface area affects the rate of reaction Aim: To investigate the factors which affect the rate of reaction between marble chips and hydrochloric acid, with one in specific detail. Scientific knowledge: To speed up the rate of a reaction, you can: * Add a catalyst * Increase the temperature * Increase the surface area * Increase the concentration These four methods all link in with the "Collision Theory" The basics of Collision Theory: Collision Theory relates to the number of molecules in the reaction, the chance of colliding correctly and the correct amount of energy. For a reaction to take place between two substances, their particles must collide, so if more collisions occur, the rate of the reaction increases. However only some collisions are successful. This is because not all particles have enough...
