Using Harvey equation 13.8, t this data to a linear curve with time t on the x axis and [ A ( t )] on the y axis. Give the line equation and calculate the standard deviations for the resulting slope k 00 (Eq. 5.16) and y-intercept [ A ] (Eq. 5.17). k 00 = _______________ k 00 = _______________ [ A ] = _______________ [ A ] = _______________ 2. With 99% condence, how long should you wait to be sure that the reaction has completed? t wait = _______________ 3. If noise in the infrared spectrometer signal has greater error as absorbances approach zero, would equations 5.16 and 5.17 still be applicable? Why or why not?
