concentration of dye

3) A student mixed a dye with bleach and monitored the reduction of the concentration of dye

 

over the course of 15 minutes under pseudo first order conditions. After plotting the results, it

 

was determined that the inverse of the concentration (in moles/L) of dye was linearly

 

dependent on time. The equation of the line of best fit was found to be:

 

y = 127.3x + 19872

 

Determine the following:

 

a) kobs (include the units) =

 

b) Order of the reaction with respect to the dye:

 

c) the initial concentration of dye

 

 

 

4) If bleach contains 5.5% NaOCl (mass/volume), what is the concentration of NaOCl in moles/L?

 

MM’s: Na = 22.99 g/mol, O = 16.00 g/mol, Cl= 35.45 g/mol
