For the reaction at const. temp.: A > B, having k = 2.26 x 103 M's', how long would it take, IN MINUTES, for [A] to decline to 0.286 M when [A] =1.00 M?4. Explain why the rate of formation of 1-azidopropane is different depending on which halopropane (X = F, Cl, Br, I) is used. Explain which halopropane will react fastest? ~X X = F, Cl, Br, I NaN №3 1-azidopropaneQUESTION 11 While examining radical halogenation reactions, we saw that different "reaction pathways" lead to the formation of different products. How does the difference in energy between the activation barriers of rate-determining steps (AAGI) for these pathways affect the selectivity of the reactions and the products that are produced? O A. The bigger the difference in energy between activation barriers results in a more selective reaction. The reaction is relatively "clean" and mostly produces one product. O B. The bigger the difference in energy between activation barriers results in a less selective reaction. The reaction is "messy" and produces a more equivalent mixture of products. O C. The smaller the difference in energy between activation barriers results in a less selective reaction. The reaction is relatively "clean" and mostly produces one product. O D. The smaller the difference in energy between activation barriers results in a more selective reaction. The reaction is…
