The decomposition of dinitrogen pentaoxide to nitrogen dioxide and oxygen follows first-order kinetics and has an activation energy of 102 kJ/mol. By what factor will the fraction of collisions with energy greater than or equal to the activation energy increase if the reaction temperature goes from 30 degree C to 60 degree C? A) 1.00 B) 1.10 C) 2.00 D) 4.00 E) 38.4 Consider the general reaction 5Br^-(aq) + BrO_3^-(aq) + 6H^+(aq) rightarrow 3Br_2(aq) + 3H_2O(aq) For this reaction, the rate when expressed as delta[Br_2]/delta t is the same as A) - delta[H_2O]/delta t B) 3 delta[BrO_3^-]/delta t C) -5 delta[Br^-]/delta t D) -0.6 delta[Br^-]/delta t E) none of the above
