- The rate of a reaction was experimentally determined to double if the concentration of reactant A is doubled. and is determined to increase 9 times when the concentration of reactant B is tripled. What is the rate law expression described above? O rate k[A][B]2 %3D rate = k[A]?[B]3 %3D rate = k[A][B]3 %3D O rate = k[A]2[B]² %3Darrow_forward8.

Increasing the concentration of a reactant always increases the rate of a reaction.arrow_forwardQUESTION 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…arrow_forward
