Question
The solutions in thls pluLaU alt. stock used 1.00 M stock solution of NaOH 6.00E-04 M stock solution of Carmine Red Note that the Beer's Law constant (s) of Carmine Red is 4.80E+04 L mol-1 cm-1 In the two runs of the reaction that are performed, each volume of stock solution used is diluted to a final volume as indicated in the table below. NOTE that this is before any mixing of the solutions occur. Run 1 Run 2 Volume NaOH stock. 4.00 mL. 8.00 mL Final Volume Diluted NaoH 50.0 mL 50.0 mL Volume CR stock 5.00 mL 5.00 mL Final Volume Diluted CR 50.0 mL. 50.0 mLExplanation / Answer
Q10
best fit is that of ln(A) vs time so
the units for k must be
1/ time
we are using seconds as untis of time so
1/s
for a first order reaction, then, units of K --> 1/s
