QUESTION:
The rate of a reaction was followed by the absorption of light by the reactants and products as a function of wavelengths (l1, l2, l3) as time progresses. Which of the following mechanisms is consistent with the experimental data? (a) A B, A C (b) A B 1 C (c) A B, B C 1 D (d) A B, B C Time 1 2 3 Light absorption 1
ANSWER:Step 1 of 2
(the absorbance of A) decreases with time. This would happen for all the mechanisms shown.
increases with time and then decreases.
Therefore, B cannot be a product as shown in mechanisms (a) or (b).
