Order and rate law of a reaction The overall order of an elementary step directly corresponds to its molecularity. Both steps in this example are second order because they are each bimolecular. Furthermore, the rate law can be determined directly from the number of each type of molecule in an elementary step. For example, the rate law for step 1 is rate = k[NO2]? The exponent "2" is used because the reaction involves two NO2 molecules. The rate law for step 2 is rate = k[NO3]'[C0]! = k[NO3][CO] because the reaction involves only one molecule of each reactant the exponents are omitted. Analyzing a new reaction Consider the following elementary steps that make up the mechanism of a certain reaction: 1. 2A→B+ C 2. B +D→E+C

In a study of the gas phase decomposition of dinitrogen pentoxide at 335 K N2O5(g) 2 NO2(g) + ½ O2(g) the concentration of N2O5 was followed as a function of time. It was found that a graph of In[N,05] versus time in seconds gave a straight line with a slope of -6.82x103 s and a y-intercept of -2.58 . Based on this plot, the reaction is first order in N205 and the half life for the reaction is seconds.
2. Imagine you run a reaction whose free energy of activation (AG*) is 18 kcal/mol. If it were a first order reaction, its’ half life (the time for half the starting material to go away) or half the product to form (assuming a 100% yield) would by In2/k where k is the rate constant. How long will it take for the reaction to be done if you run the reaction in an ice-salt bath at room temperature (20 °C) if the rate constant were 1 x 104/sec?
