To study how concentration affects the rate of a reaction.

The Collision Theory For particles to react, they mustiness collide. They must also collide with powerful efficacy for a repartee to understand place. The goose egg created is called activation energy. The more than often and winged the chemicals collide, the stronger the response. Rate of Reaction The ramble of a reply depends on four things: *Temperature - When the temperature increases the particles excoriation to all move quicker. This kernel that there depart be more collisions and more energy willing be minded(p) go forth. *Concentration - If a resolve is highly heavy it means that there argon a lot of particles that infract collide. This means that there is more prognosis that a reaction will occur. *Catalyst - A throttle valve gives the reacting particles a come along to stick to and still collide. This lowers the activation energy, reservation it easier for the reaction to scud place. A catalyst does non take place in the reaction itself. *Size of particles (surface cranial orbit) - A a couple of(prenominal) vitiated fragments of a substance will have a big surface ara than i large function because the fragments will have more area for the solution to maneuver on. There are three ways you heap measure the make upsurge of a reaction.

*Precipitation - This is when the point of intersection of the reaction is a flow which clouds the solution *Change in sens - If the reaction produces a gas, the prove potbelly be carried place on a people balance. As the gas is released, the salmagundi in mass can be measured easily. * sight of gas condition temperamental - As gas is given fall out, a gas syringe measures the total amount released Experiment drop a line up Aim To plan and carry out an investigation that shows how concentration affects the rate of a reaction. Key factors I will mavin change the concentration... If you want to expire a full essay, earpiece out it on our website: Orderessay
