Chemistry coursework rate of reaction conclusion

Introduction: the rate at which an object cools (ie how quickly its temperature decreases) depends upon several factors, including: surface area volume type cooling-rate-graph conclusion: there is a strong correlation between the average rate of cooling and the start temperature: the greater the start temperature, the. My investigation is about the rate of reaction a rate of reaction is defined as how fast or slow a reaction takes place for example, the oxidation of iron under the atmosphere is a slow reaction which can take many years, but the combustion of butane in a fire is a reaction that takes place in fractions of a second.
