Suppose the rate law for particular reaction between nitrogen dioxide and chlorine is Rate = K[NO_2]^2[Cl_2]. How would each of the following affect the rate of the reaction? a). If the concentration of NO_2 is triples, then the reaction rate would (increase/decrease?) _____ by a factor of _____. b). If the concentration of NO_2 and Cl_2 are both doubled, then the reaction rate would (increase/decrease?) _____ by a factor of _____. If the concentration of CL_2 is halved, then the reaction rate would (increase/decrease?) ______ by a factor of _____. Use the rate law to explain quantitatively how decreasing the iodine ion concentration affects the rate of iodine clock reaction? (State whether it doubles or triples, etc.) Use the rate law to explain quantitatively how increasing the bisulfite ion concentration affects the rate of iodine clock reaction? (Again, state whether it doubles or triples, etc.). How would doubling the total volume of the solution by doubling the volume of water, iodate and bisulfite solutions affect the rate of the iodine clock reaction? Explain in full sentences. Why is it important to record the temperature when you did not have to use it in any of your calculations? Explain in full sentences. Explain, at the particulate level, why increasing the concentrations of the reactants would cause an increase in the rate of the reaction. (Think carefully what is meant by "at the particulate level.")
