To study how concentration affects the rate of a reaction.

The Collision Theory For particles to react, they must bump around. They must also collide with decent efficacy for a reply to understand place. The strength created is called activation energy. The more often and faster the chemicals collide, the stronger the chemical chemical reaction. Rate of chemical reaction The rate of a reaction depends on four things: *Temperature - When the temperature increases the particles commencement to all move quicker. This meaning that there leave alone be more collisions and more energy depart be given(p) go forth. *Concentration - If a resolve is highly change state it means that there are a lot of particles that sugar collide. This means that there is more prognosis that a reaction will occur. *Catalyst - A throttle valve gives the reacting particles a come to stick to and still collide. This lowers the activation energy, reservation it easier for the reaction to contact place. A catalyst does not take place in the react ion itself. *Size of particles (surface area) - A a couple of(prenominal) dinky fragments of a substance will have a large 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 begin 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 spatter, 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 th! e total amount released Experiment save up Aim To plan and carry out an investigation that shows how concentration affects the rate of a reaction. Key factors I will single change the concentration... If you want to get a beneficial essay, sound out it on our website: OrderCustomPaper.com
