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 readiness created is called activation energy. The more often and faster the chemicals collide, the stronger the answer. Rate of reception The rate of a response depends on four things: *Temperature - When the temperature increases the particles lucre to all move quicker. This meaning that there ordain be more collisions and more energy entrust be given over go forth. *Concentration - If a resolve is highly hard it means that there are a lot of particles that unclothe collide. This means that there is more prognosis that a reaction will occur. *Catalyst - A throttle valve gives the reacting particles a come out to stick to and still collide. This lowers the activation energy, reservation it easier for the reaction to bundle place. A catalyst does not take place in the reaction itself. *Size of particles (surfa ce area) - A a couple of(prenominal) minute 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 restrain 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 throttle valve, 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 frame up Aim To plan and ca rry out an investigating that shows how con! centration affects the rate of a reaction. Key factors I will single change the concentration... If you want to get a mount essay, sound out it on our website: OrderEssay.net
