Help!!!

Is it reasonable to assume that the reaction velocity is directly proportional to absorbance? CAREFULLY explain your reasoning. How could you determine whether this was the case? (15 marks)
Hi,

If a product of a reaction has a colour AND the product is soluble, then of course, the intensity of the colour of the solution that absorbs light of the wavelength concerned, can be expected to be proportional to the amount of product generated, which, assuming all other factors are taken into account, would, in turn, be proportional to the rate of reaction.

For the 2nd part, just describe an experiment using your knowledge of biology and/or chemistry, mentioning the logic, the safety measures and what is taught these days, in baby language, as "fair test" - I am not going to do that for you!

Thanks!
M
