Problem 2

From Figs, 6.2 and 6.3, determine the values of $v_{\max }$ and $K_m$. The straight lines drawn "by eye" go through the points $(-0.0094,0)$ and $(0.04,0.35)$ (Lineweaver-Burk), $(0.04,0.35)$ and $(15,0.007)$ (Eadie-Hofstee); $(0,7.5)$ and $(500,39)$ (Hanes).

Problem 3

Draw the best straight line through the data points of the logarithmic graph of $k$ versus $1000 / T$, made in Exercise 3.2 (page 25). Determine the constant $E$ in the relation $k=A \exp (-E / R T)$ (which units?). Estimate the inaccuracy in $E$.

Problem 4

Using Fig. 6.8, determine the concentration (with s.d.) when the measured optical density equals $1.38 \pm 0.01$, assuming that the calibration error is negligible.
