The reaction below was monitored as a function of time: AB A + B A plot of ln[AB] vs. time yields a straight line with slope = -0.0025 sec-1 . a) What is the value of the rate constant (k) for this reaction at this temperature? b) Write the rate law for this reaction. c) What is the half-life (t1/2)? d) If the initial concentration of AB is 0.500 M, what is the concentration after 300 sec?
Most of the time, the rate of a reaction depends on the
concentration of the reactant. In the case of second-order
reactions, the rate is proportional to the square of the
concentration of the reactant.
Select the image to explore the simulation, which will help you
to understand how second-order reactions are identified by the

Perform a linear regression to determine the slope of the plot of Ln(A/A0) vs time that is discussed on page 16. Recall from page 12 that the slope for this plot is -k (where k is the radioactive decay constant). Input below the value for k obtained from this data set. Answer=0.0715 Note that your k value should be positive, since it is the negative of the slope. All reaction rate constants are positive values. The units for this k...
