Question
Which aqueous solution will have the lowest freezing point? 0.040 m glucose 0.025 m KBr 0.020 m Nacl 0.020 m BaCl2 What is the rate law for the reaction? C2H6O2 + 3Br2 rightarrow C3H4Br2O2 + 2HBr rate= k[C2H6O2][Br2]2 rate= k[C2H6O2][Br2] rate = k[C2H6O2]2 rate = k[C2H6O2] Which rate law corresponds to the proposed mechanism for the decomposing of N2O? Rate - k[N2O] Rate - k[N2O]2 Rate - k[N2O][O] Rate - k[N2o]2[O] The main reason that reaction rates normally decrease as the temperature is decreased is that the energy of molecular collisions decreases as the temperature decreases. activation energy increases as the temperature decreases equilibrium constant increases as the temperature decreases. all the above.Explanation / Answer
