試題詳解

1. For the reaction 2N₂O₅(g) 4NO₂(g) + O₂(g). (AB) The amount of NO₂ in the reaction container is four times the amount of O₂regardless how the reaction mixture is prepared for the reaction to oceur. (AC)At the moment when N₂O₅(g) is first transferred to the empty reaction container. the rate of disappearance of N₂O₅ is more than two times the rate of formation of O₂. (AD) At any instant. the rate of formation of NO₂ is two times the rate of disappearance of N₂O₅. (AE) The reaction is a second-order reaction. just like any reactions of 2M₂N₅ → 4MN₂ + N₂. (BC)If the measured initial rates are M/sec for the initial concentrations of N₂O₅ of 0.0050 M and 0.010 M. respectively, the overall reaction order is one. (BD) The activation energy of the reaction may be derived from measuring the rate constants at two different temperatures.
