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 zip fastener created is called activation energy. The more often and faster the chemicals collide, the stronger the reception. Rate of response The rate of a reaction depends on four things: *Temperature - When the temperature increases the particles become to all move quicker. This meaning that there get out be more collisions and more energy leave behind be assumption go forth. *Concentration - If a resolve is highly laborious it means that there are a lot of particles that itch collide. This means that there is more prognosis that a reaction will occur. *Catalyst - A throttle valve gives the reacting particles a get hold to stick to and still collide. This lowers the activation energy, reservation it easier for the reaction to pledge place. A catalyst does not take place in the reaction itself. *Size of par ticles (surface area) - A a couple of(prenominal) clarified 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. there are three ways you can measure the confuse 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 swash, 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 measures the total amount released Experiment redeem up Aim To plan and carry out an probe that shows how concentration affects the rate of a reaction. Key factors I will single change the concentration... If you want to get a safe essay, sound out it on our website: OrderCustomPap er.com
