1. The concentration of the solution affects how much light of a certain wavelength is able to pass through the solution. The more concentrated the solution is, the less light willpass and therefore the higher the absorbance of that solution is. The Beer-Lambert law forabsorbance is Acl,wherecis the concentration, lis the path length, and ε is a constant of proportionality known as the molar extinction coefficient.There is a linear relationshipbetween absorbance and the concentration of the absorbing solution according to the Beer-Lambert law.2. Reaction ratefor a reactant or product in a particular reaction is defined as the amount of the chemical that is formed or removed (in moles or mass units) per unit time per unit volume.In chemical kinetics areaction rate constantquantifies the speed of a chemical reaction. k is a proportionality constant that does not change for a reaction at a constant temperature.
