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 mL

Explanation / 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
