POST LAB I 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. Note: This constant is sometimes referred to as the pseudo rate constant, because it does not take into account the effect of the other reactant, OH Follow your teacher's instructions to share your value of the rate constant with the rest of the dass so they may use it in their entor analysis. 3. Why was it necessary to record the room temperature when conducting this lab? 4. Write the correct rate law expression for the reaction, in terms of crystal violet (omitting OH) 5. Why are we unconcemed with the rate of the reaction with respect to hydroxide in this experiment? Explain 6 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 (or 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) Give this value with the appropriate units 7. Write a conclusion including error analysis
