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 rate of reaction
Variables:
Possible variables that could speed up the rate of a reaction are;
Temperature
Catalyst
Surface area
Concentration
Chosen Variable= Concentration=Independent Variable
Scientific knowledge:
Reactions can go at all 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 observed either by how quickly the reactants are used or how quickly the products are forming. For this experiment I will be observing…
