Graphical Representation
*(c) (/) Using the method of least squares, find the equation of the best-fit line
for the data as plotted in (a) above, (ii) Find the correlation coefficient
and the 95% confidence intervals for both the slope and the y intercept of
the best-fit equation. (Hi) On the plot made in (a), draw the line that
corresponds to the best-fit equation.
(d) Calculate the value of the "energy of reaction" for this reaction.
(e) What is the physical significance of the constant Z?
