Science-chemistry practical-To find out how the concentrations of the reactants affect the rate of reaction

Aim: To find push through how the concentrations of the reactants affect the station of receipt Variables: Possible variables that could speed up the consider of a response ar; Temperature Catalyst Surface area tautness elect Variable= Concentration=Independent Variable Scientific association: Reactions can go at any sorts of different place e.g. a slow reply would be the rusting of atomic number 26 and a really fast reaction is an explosion. The speed of a reaction can be find either by how quickly the reactants are r bug outined or how quickly the products are forming. For this sample I bequeath be observing how quickly the reactants are forming (how quickly the radical turns opaque white), this is because this method is a stria easier to measure. This is called the precipitation method. It is when the product of the reaction is a precipitate, which clouds the solution and is carried out by observing a marker through the solution and measure how long it take s to disappear. opposite methods include finding out the change in plentifulness by using a mass balance and running(a) out the volume of gas given up off with the use of a gas syringe. Reaction grade are explained by the bang Theory, which explains that the rate of reaction depends on how often and how hard the reacting particles bump around with each other. The particles prepare to collide with each other, hard decent in localise to react. Therefore more collisions increase the rate of reaction. The factors that affect rate of reaction include temperature, increasing the temperature hits the particles stir up speedy and collide more. At a higher temperature thither will be more particles colliding with enough aptitude to make the reaction happen. The initial energy is known as the activating energy and its needed to break the initial bonds. However in this experiment...
