Question

Using the Beer's Law plots constructed for TZ and AR at 430 and 480 nm (including the one you previously constructed for Part III), please report the respective effective molar absorptivities (ε∗,L/μmolε∗,L/μmol), which is represented the slope of the linear trendline through the data on each plot.

	Unrounded	Rounded
TZ Effective Molar Absorptivity at 430, ε∗(L/μmol)ε∗(L/μmol)	0.0259825	0.0260
TZ Effective Molar Absorptivity at 480, ε∗(L/μmol)ε∗(L/μmol)
AR Effective Molar Absorptivity at 430 nm, ε∗(L/μmol)ε∗(L/μmol)
