Question: I need help with Crystal Lab The assignment is due today I posted like 2 times and I really need the answer Please help me


1. Was the reaction zero, first, or second order, with respect to the concentration of crystal violet? Explain. 2. Calculate the rate constant, k, using the slope of the linear regression line for your linear curve (k= slope for zero and first order and k= slope for second order). Be sure to include correct units for the rate constant. This constant is referred to as the pseudo rate constont because it does not take into account the effect of the other reactant, OH. 3. Write the correct rate law expression for the reaction; in terms of erystal violet (omit OH ). 4. Using the printed data table, estimate the half-life of the reaction; select two points, one with an absorbance value that is about half of the other absorbance value. The time it takes the absorbance for concentration) to be halved is known the half-life for the reaction. (As an alternative, you may choose to calculate the half-life from the rate constant, k, using the appropriate concentration-time formula.) 5. Explain why absorbance measures can be used in determining rate laws. Shent1: clothing.
