Many people are interested to know how to alter the rates of chemical reactions. Fertiliser manufacturers are interested in speeding up the formation of ammonia from nitrogen and hydrogen. Car manufacturers are interested in slowing down the rate at which iron rusts. This shows that rates of reaction is a very important factor within industries today, and in order to demonstrate how a particular factor can alter the speed of a reaction the outcome variable of my investigation to follow is: How a chosen factor affects the rate of reaction of Magnesium and Hydrochloric Acid.

Reaching this outcome will consist of choosing a relevant factor with the assist of background knowledge, applying the factor whilst experimenting, measuring the rate of reaction and concluding the outcome. In order to choose a relevant factor I will initially need to observe the different variables:

1. The concentration of a reactant.

The higher...
