For example, some evidence that a chemical reaction has occurred is possible changes in energy, release of energy, formation of a new substance, or reduction or increase in temperature.
There are many things that can affect the rate of reaction, (some of these are shown in figure 1 below.) In this coursework I am going to investigate what effect the change in acid concentration has on a chemical reaction....

Chemical reactions can characterized as irreversible, reversible, or oscillating. In the former case, the equilibrium for the reaction highly favors formation of the products, and only a very small amount of reactants remains in the system at equilibrium. In contrast to this, a reversible reaction allows for appreciable quantities of all reactants and products co-existing at equilibrium. HO + 3NO &NA; 2HNO + NO is an example of a reversible reaction. In an oscillating chemical reaction, the concentrations of the reactants and products change with in a periodic or quasi-periodic manner. Chemical oscillators exhibit chaotic behavior, in which concentrations of products and the course of a reaction depend on the initial conditions of the reaction.
