    higher the value of the reaction order the larger the effect of that specie’s concentration on the rate of the reaction. So for the chemical equation for this experiment: The reaction rate is: . Due to the fact that alcohol is found in excess in this reaction it can be removed from the expression‚ leaving the expression: Beers Law states that the amount of light absorbed is proportional to the concentration of a species‚ in this case (3). Where A is the measure of absorbance. Ԑ is the molar
