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

Aim:

To find out how the concentrations of the reactants affect the station of reception

Variables:

Possible variables that could speed up the rate of a reaction are;

Temperature

Catalyst

Surface area

tautness

Chosen Variable= Concentration=Independent Variable

Scientific knowledge:

Reactions can go at any sorts of different rates e.g. a slow reaction would be the rusting of iron and a really fast reaction is an explosion. The speed of a reaction can be find either by how quickly the reactants are routined or how quickly the products are forming. For this experiment I will be observing how quickly the reactants are forming (how quickly the solution turns opaque white), this is because this method is a lot 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 takes 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 off with the use of a gas syringe.

Reaction rates 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 have to collide with each other, hard decent in order 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 quicker and collide more. At a higher temperature thither will be more particles colliding with enough energy 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...
