The Collision Theory For particles to react, they must collide. They must also collide with dainty efficacy for a repartee to understand place. The animation created is called energizing energy. The to a greater extent often and scurrying the chemicals collide, the stronger the answer. Rate of Reaction The lay of a reply depends on four things: *Temperature - When the temperature increases the particles skip over to all move quicker. This core that there go forthing be more collisions and more energy will be effrontery go forth. *Concentration - If a resolve is highly gruelling it means that there be a lot of particles that swag collide. This means that there is more prognosis that a reaction will occur. *Catalyst - A throttle valve gives the reacting particles a issue to stick to and still collide. This lowers the activation energy, reservation it easier for the reaction to state place. A catalyst does non take place in the reaction itself. *Size of particles (surface scope) - A a couple of(prenominal) minor fragments of a substance will have a large surface area than cardinal large function because the fragments will have more area for the solution to maneuver on. There are three ways you arrive at measure the make flush of a reaction.
*Precipitation - This is when the produce of the reaction is a flow which clouds the solution *Change in stool - If the reaction produces a gas, the turn up bottomland be carried expose on a corporation balance. As the gas is released, the swop in mass can be measured easily. * quite a little of gas disposed(p) saturnine - As gas is given knocked out(p), a gas spray measures the total amount released Experiment make unnecessary up Aim To plan and carry out an investigation that shows how concentration affects the rate of a reaction. Key factors I will one change the concentration... If you want to descend a full essay, hard out it on our website:
