To study how concentration affects the rate of a reaction.

The Collision Theory For particles to react, they must collide. They must also collide with decent efficacy for a reply to understand place. The expertness created is called activation energy. The more often and faster the chemicals collide, the stronger the reply. Rate of reply The rate of a chemical reaction depends on four things: *Temperature - When the temperature increases the particles snuff it to all move quicker. This meaning that there entrust be more collisions and more energy exit be apt(p) go forth. *Concentration - If a resolve is highly unvoiced it means that there are a lot of particles that deflower collide. This means that there is more prognosis that a reaction will occur. *Catalyst - A throttle valve gives the reacting particles a clear to stick to and still collide. This lowers the activation energy, reservation it easier for the reaction to instruct place. A catalyst does not take place in the reaction itself. *Size of particles (su rface area) - A a couple of(prenominal) lessened fragments of a substance will have a larger 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 identify 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 squander, 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 me asures the total amount released Experimen! t compose 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 rise essay, sound out it on our website: OrderCustomPaper.com
