Chemistry Coursework- To Investigate Rates of Reaction Plan The rate of reaction is the speed at which a reaction takes place. For a reaction to occur, bonds must be broken. A certain amount of energy is needed to do this, known as the activation energy (Ea). The kinetic theory states that all matter is in a constant state of movement, and due to this, particles collide. These collisions produce energy, and when there is enough, the bonds of a molecule are broken. The rate of a reaction is effected by three main factors: 1. The concentration of the reactants- with a higher concentration of particles, there are more chances for collisions to occur. 2. The temperature at which the reaction takes place- at a higher temperature, particles have more kinetic energy, so there are more collisions, and they are more energetic. 3. If a catalyst is used, it provides a reaction path that requires a...
