Coursework Rates of Reaction PLAN Introduction AIM - The aim of this experiment is to investigate the factor(s) affecting the rate of reaction when magnesium is reacted with dilute hydrochloric acid. Background knowledge This reaction takes place when particles collide with sufficient energy. Variables - There are 6 main variables that you can change to increase the rate of reaction: • TEMPERATURE - increasing temperature gives the particles more energy making them faster and will travel over a great distance in a given time and can collide easier overcoming activation energy. • CONCENTRATION - increasing concentration means more particles in a given area making them easier to collide. • STIRRING - stirring will make the particles move around more and help them collide with each other easier. • CATALYST - catalyst is a substance, which increases the rate of reaction but itself remains the same. Catalyst reduces the activation energy making the reaction quicker. • SURFACE AREA - increasing the surface are by...
