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...

For a 1st order reaction the logarithm of concentration is linear to time. The linear equation of the following curve is lnC = lnC0 – 0.2t; where C is the molar concentration (M) of a reactant, C0 is the molar concentration at time t = 0 (the starting concentration or the initial concentration), and in this particular case C0 = 10 M; and t is time in seconds. What is the slope (and the unit) of the curve? What will...
