Chemistry coursework rate of reaction introduction

Introduction 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. The reaction rate or rate of reaction is the speed at which reactants are converted into products for example, the oxidative rusting of iron under earth's atmosphere is a slow reaction that can take many years, but the combustion of cellulose in a fire is a reaction that takes place in fractions of a second for most reactions, the.
