Questions for Crystal Violet Lab.

  1. Give the derivation of a first order rate equation and show why the plots of Ln ([dye]o/[dye]t) vs t should be linear.

  1. What property other than [dye]t and [dye]o could have been used for the plot of Ln ([dye]o/[dye]t) vs t? Explain your answer.

Solutions

Expert Solution

For the 1st part, just integrate the differential form of rate equation to get the integrated form and compare it with a general equation of a strain line to see whether it is linear or not (Spoiler alert: it is linear).

Use Beer-Lambert law to change the concentration terms to corresponding absorbance terms.

The indicator crystal violet, (V) reacts with NaOH (OH- ) according to the equation: CV(aq) + OH- (aq) → CV- (aq) (Violet) (Colorless) The rate law for the reaction is: Rate = k2 [CV] [NaOH]. In an experiment the concentration of NaOH exceeds that of the crystal violet by a factor of 1000 so the rate law becomes Rate = k1 [CV] where k1 = k2 [NaOH] . The following data were obtained for the reaction of crystal violet with...

Bragg's Equation Problem X-rays of wavelength .0960nm are diffracted by a metallic crystal, angle of first order (n=1), is measured to be 17.8. What is the distance (in pm) between the layers of atoms responsible for diffraction? I do this: 96pm / 2sin17.8 and I keep getting ~173.9pm The answer is supposed to be 157pm. What am I doing wrong?
