Unformatted text preview: 3. The rate equations are A and B are reactants, C is an intermediate and P is a product. 4. Using the first piece of data and the Arrhenius equation, we have The second data point gives us Subtract the two equations to eliminate : Now substitute this data back into one of the two original equations, say the first one: 1. The halflife is the time required for half the original quantity of a reactant to be removed. 2. At , . Substituting these values into the thirdorder equation, we have 3. The rate constant for a thirdorder process is in . 4. If we plot as a function of time, we get a straight line of slope 2 k . The rate constant is therefore extracted by dividing the slope of the plot by 2. Marc Roussel Thu Sep 26 13:13:23 MDT 1996...
