Suppose that in the reaction Q + R --> P, only the product, P, is colored. What happens to the absorbance at the analytical wavelength for P of the mixture as the reaction progresses? Suppose you do an experiment involving this reaction in which Q is present in large excess of R. If this reaction is first order with respect to R, would the graph of ln A for P versus time be straight line? Explain.
