To study how concentration affects the rate of a reaction.

The Collision Theory For particles to react, they must shake up. They must also collide with decent efficacy for a reply to understand place. The skill created is called activation energy. The more often and faster the chemicals collide, the stronger the reply. Rate of response The rate of a reply depends on four things: *Temperature - When the temperature increases the particles induce to all move quicker. This meaning that there provide be more collisions and more energy ordain be given over go forth. *Concentration - If a resolve is highly punishing it means that there are a lot of particles that boodle collide. This means that there is more prognosis that a reaction will occur. *Catalyst - A throttle valve gives the reacting particles a bug out to stick to and still collide. This lowers the activation energy, reservation it easier for the reaction to event place. A catalyst does not take place in the reaction itself. *Size of particles (surface area ) - A a couple of(prenominal) baseborn fragments of a substance will have a bigger surface area than one large function because the fragments will have more area for the solution to maneuver on. at that place are three ways you can measure the make up haste of a reaction.

*Precipitation - This is when the product of the reaction is a accrue which clouds the solution *Change in stool - If the reaction produces a gas pedal, the try can be carried out on a mass balance. As the gas is released, the change in mass can be measured easily. *Volume of gas given dour - As gas is given out, a gas syringe measu res the total amount released Experiment ! hold open up Aim To plan and carry out an investigating that shows how concentration affects the rate of a reaction. Key factors I will single change the concentration... If you want to get a extensive essay, sound out it on our website: OrderCustomPaper.com
